@@skelldogTalo Lately I tried to compare antennas with DJI FPV goggles (because with digital you get Logfiles). these logfiles can be analyzed in Excel. see my last few videos about this. so far I didnt find the perfect test-setup to get good and distinct results...
I'm a big fan of helicals, they always outperform my small patches. I have made over a dozen varieties and find the best overall balance is around 4.5 turn. They are very tricky to tune properly, and it's very obvious once you do it, that's where the high price comes from. It simply cannot be done on a mass production line and requires a lot of time to get right, yet tuned or untuned they will still look identical - until you use them. Great test review Mario, thanks.
thanks for your experience. I saw that cheap helicals can be really bad - even if they look no different than the expensive ones (I think I had one in 2018 video from hobbyking, dirt cheap). Also: I think the lower turn ORT 6.5 performed better than the CWL 7.5 and I'm not 100% sure if I count the turns correct :)
I seem to have to same issue as you have: mostly "outaTime". But here I forced myself to spend this hour up their and I'm so happy that I could finally do this 2nd test. I learned a few things again - and my next test will be better. Probbably not before spring tho :)
That's a lot of antennas, i appreciate the video index in the video description but i think you should also post it in the comment section and pin that comment ;) Have a great weekend Mario and keep it up the great job
Thank's Cedric, good idea. Btw: I found out, I can export text markers from my Vegas timeline in text format and paste them here. Wish I knew this earlier ;)
A big THANK YOU and hats off to Mario !! Just to be picky ... given the power increase ratio (~1.26) from tests beginning to end, 1 dB should be added in absolute value to the final results .... isn't it ?
this time I didnt chech the power output of the TX. But also: this time it was ~7°C and windy - so maybe the TX was cooled enough to have a quite constant output. On the bench I found a good correlation between heat and degradiation of RF power. But it took 40 or 50°C to see a decrease of RF power...
Nice to see such positive feedback right away. I guess this is of interest for most FPVers - since a lot of times we have to guess which antennas are really as good as advertised... rf stuff is difficult :)
wow you're the mvp of antenna reviews. why is nobody else doing this testing? I find it quite curious that the latest lollipop antennae seem to do worse, any idea why? or are there other factors making them better in practice?
hi, thanks. the newer (back then) lollis were just made cheaper - that's why their performance dropped. Newer products are not always an improvement (of course marketing always suggests this) sometimes they are just cheaper to make. Of like with the DJI cams: because some chips are not available - other ones have to be used (but those other cams are not as good as the OG DJI cams :)
Yea, I think the french guy, RedBaron did test those antennas. Do you know his tests? Forgot his name, but search RedBaron and antennatest - he has a nice series...
@@mikeellicott6977 for sure - they are in fact way more "real life" than my test here! check it out here: ua-cam.com/video/eWlLO6QqxGg/v-deo.html It's Marc Porral / RedBaron
Excellent consistent list, I can find an optimal antenna in a few seconds! You should do propeller--motor thrust tests. MiniQuadTestBench still doesn't use Gemfan Hulkie 5055 or Flash 6042 in any tests. You'd rock at filling the gaps there.
Thanks for the tip. Any excuse to buy another measurement device is welcome ;) When it comes to props I don't know much yet. Mostly fly the same dalprops since foxeer sent me many of them..
Love your testing! Can I advise a small tweak to your testing methodology that will help give you larger # spreads on your omni’s and truely show which are better? Space your RX at a larger distance to the point where the worst antenna of your batch is showing 81-82 in the null zone, rather than no antenna in the null zone distance. This greater separation (might be 10m+) will give you much more accurate and easily rateable rankings for which antennas are truly better than the others. Thanks again Schim!!
I agree. That's what I meant, I'd like to have way more time for such test session... For your suggestion I need to know which antenna is the worst performer and set the distance according to this. Maybe I should make 2 groups: omnis at closer range and directional antennas in their own class where the distance is a few hundret meters (even when using only 1mw transmit power). thanks for the feedback - I like the challenge :)
Totally!! That’s exactly what I would do. Max-our your poorest omni for range @ 81db and then run all your omni tests from that point. Then have a second test group just for directional antennas at a range that also maxes out the “worst” directional antenna @ 1mW. Great testing Shim! I wish I had some extra Axii 2 & Axii micros to send you to test alongside those lollipops as it’s interesting how every revision of lollipop appears to have slightly worse range. Haha. For omni’s my personal favorite on the goggles are the pagoda 2 (open air) and the VAS Ion/Minion. For patches the TrueRC Air2 (pepperbox) for the performance and the menaceRC patches for their size. Thanks again Shim! Love your videos & testing! - Travis
thanks for suggestions. always nice to see what you guys use. Orqa goggles? there's quite a hype about them right now, right? I didnt even check their specs. Will do my homework soon :)
@@Rcschim yeah, I received my Orqa goggles last Monday (tl;dr: awesome & evolving quickly) with the pro antennas, so was wondering how well they performed in various scenarios 😅
Ja, aber geschmiedete Antennen klingen doch viel zu schwer für unsere kleinen Copter :) Ich geb zu - ich hab hier für den Test einfach die Antennen genommen, welche ich so gesammelt hab. Versuchte schon ein paar Hersteller anzuschreiben, bekam aber ausser von Banggood und ORT keine Review-Samples. Und alle möglichen Antennen selbst zu kaufen, dafür reicht das UA-cam-money leider bei weitem nicht :)
Bitte gern, war interessant zu sehen, wie die einzelnen, doch recht gleichen Antennen untereinander abschneiden und hilft mir selbst auch, zu entscheiden, welche Antennen jetzt auf die Fatshark drauf kommen (oder später dann auf die DJI)
Ty,exactly whatvIbwas looking for. Real measurments and numbers, good work 🛰️📊👍 I spend all my money for my first diy-drone & all the rest, but when I have some over I send you some antennas to test. Good to know if cheap Chinaantennas are a good alternative
After thoroughly studying your excellent Excel spreadsheet, it is kind of amazing that none of the omni antenna's are really any different in performance from one another! Sure, the old blue Aomway gets a score of -58, but none of the others are much worse than -60 !! I guess the ORT 6Lobe SPW is slightly better, but not enough to pay it's price since I have a perfectly good blue Aomway. I find the difference between any of the omni's to be pretty insignificant, don't you think? (except for the Thor and some other old ball ones that aren't that popular). I also found it weird that the further we get into the Foxeer lollipop line, 1, 2, and 3...the WORSE they get! Course the best is the first one, and you can't buy it anywhere! lol D'oh! I think I'll stick with the blue Aomway and the Triple Feed Patch 9.4dB on the other side. That one appears to be the BEST BUY of any of these, at under 11 bucks! Great Review my friend! Thanks for all of your time and efforts!!! =(:^)-
I remeber that I paid 64€ for the circular wireless antennas back a few years ago. and even this money wasnt wasted - they gave me good confidence while flying further out an expensive model... And: as alisdair... commented: it's really hard work to make a well tuned helical - not easy to make them in large number with good quality. they need to be hand- tuned to work that well...
The only problem in this test is that it is done for 1 frequency only. the 5.8ghz band is pretty wide. A well tuned antenna on it's center freq, can give way more gains than a wide band antenna. A well tuned antenna but used at the wrong frequency, than were it is tuned for could perform bad, while it can be a great antenna. So if you want to to get the best antenna, buy a custom tuned antenna for your frequency. The custom tuning and measuring and small tolerances is what good antennas makes expensive.
Also because tolerances are very small, it is also questionable if factory made generic untuned antennas are peaking at the same frequency, or if there can be significant differences between different antennas.
yep, and if they are not to be sold seperatly from the goggles - i'd take the goggles as well and would take a look at them :) Seriously: I'll try to get more antennas over the next weeks and test more...
I bought their promotional video patch a while ago when they first came on the scene, they claimed a good performance, I use it all the time but I only have a few patches inc the crappy aomaway patch that came with goggles so have no real comparison, looking forward to you additional reviews in due course, I’m really wondering whether to go ORCA or DJI now, saving up so still have time, keep up the good work, I really enjoy your tube.
@@wezcrutchfield It's a tough descision. I dont know if DJI will superseed all my analog video gear already. atm I'm all on DJI and dont wanna fly analog. But on a nice sunny day, enough batteries and my trusty little freestyle SpeedyBee - I could fall for the simple analog video again. Bardwells goggles Review was good - but even he struggled to give a definitive recommendation... The Orqua with wifi and future proof cpu power and everything - they for sure go a different path than the isolated DJI fpv system. If DJI succeeds - it's ok and all we need... only time will tell - most important thing: have fun in the air! greets, Mario
you have to see the positive sides Mario: if it rains, this normally means your surrounding nature is lush of green plants rather then a desert, right? :) wish you a nice weather spring soon tho!
A lot of pilots use 90 degree connectors and even less use 45 degree or straight out of googles. Can you talk about amount of loss from different angle connectors?
I'd really like to get an opinion on the difference between the Dual Shield versus the TrueRC MX-Air Array. The MX-Air have less power but are double the price and four times as big as the Dual Shield... TrueRC builds quality stuff though.
I'll try to get some for my next video (which is actually planned to shoot soon). but currently I have to by most antennas myself. except foxeer (but they arent always good) or other stuff I can get from banggood... still have a lot of antennas in my antenna-bag to test :)
I suggest you not spin the whole antenna when you put them on. It's destroying the stinger and especially stinger receiver. Insert the antenna, then twist the outside nut so to not damage the antennas. Anyways thanks for the review.
I fly but don't understand antenna specs. Based on this list, what would be an optimal set up for flying in slightly wooded areas with a few trees. Some may be thick with a lot of leaves while others would have a lot of dry branches. I use an IRC Omni and IRC patch on the goggles, with an IRC Tramp vtx with a Foxeer Lollipop antenna. Sometimes the video breakup can be crazy. As long as I keep the quad in front of me, most of the time the video is fine. Also, I'm not using a capacitor if that means anything.
do you use RapidFire on your goggles? that could help alot :) also if you do: make sure RapidFire is calibrated (mine wasnt and my breakup was worse than it should have been). IRC omni could be swapped for example to this Foxeer Pagoda pro on the long cable - it was quite good from the numbers. IRC 8dbi patch is pretty good - not sure if another patch would give you better results. maybe consider the 3turn ORT helix - it looked really good!
@@Rcschim No, I use the La Forge diversity module. However, I'll look into Foxeer Pagoda. I was also considering the Luminier AXii Omni and their patch with a matching omni on the quad. The one on the goggles would have an extended cable. The helix may be an option for the patch. I may have to try combinations with a higher output to see what gets me the least breakup.
Just can't keep your mouth shut about the DJI. :D It's just that good. NOT hype folks! When comparing the helicals, you state that the 6 turn isn't that much better than the 3 turn. However, there is 4db of difference. That's actually quite huge since 3db is double. I know you'd probably get hazed for doing it, but it might be helpful to throw all of the numbers in a db-to-mw converter just so you can see them on a linear scale. In one of the VAS videos, he talks about the shape of the helical polarization not being as circular as he'd like. So I'm wondering if the VAS antennas may excel in a more noisy environment, whereas the helicals are better at long range where you generally keep line-of-sight. I definitely want to try the ORT 3 turns through heavy trees. But with DJI,.. I need 4 of them,. so it will have to be when I have money burning a hole in my pocket. Right now I'm running VAS SkyHammers.
Thanks for your feedback - db to mw in a seperate column in XLS sheet - good Idea - will do. Good points about that few db - sometimes we tend to forget this... The thing is: RF theory and it's practical application are extremly complex with so many factors. Tests like this here always have to be extremly oversimplified - and only pick one aspect of the antenna. I'm quite sure that the VAS antenna HAS TO BE good. I just didnt use it in a way yet so it would convince me :) So for guys like me - the allround antennas are for sure better... Not sure if I want 4 helicals on that DJI goggles - it makes you look damn stupid again - whereas the current stock antennas look kinda cool :)
@@Rcschim Haha,.... embrace the geekiness! I'll admit, 4 helicals on the goggles does give me pause. But I've also used the VAS cyclops,.....which is extremely ugly. So yeah, I have a fairly decent collection of VAS antennas. My thoughts are that the patches are only slightly above average, but the omnis seem to be quite good. I'm currently running 4 SkyHammer's on the goggles, and 2 Minion Pro's on the quad. This setup seems to keep me locked at 25Mbit's for 95% of my flight paths. It's not long distance though. Just lots of obstacles. The stock antennas do seem to do quite well if you're not really pushing the limits, which we don't most of the time. One thing several of us found, was that the stock antennas are barely circular polarized. We've switched out the quad antennas for RHCP, and left the stock antennas on the goggle, and there is no difference. Some think the stock antennas are better than many of the omnis, but my testing with aftermarket omnis shows a definite improvement.
RC Shim....I have been using a VAS crosshair extreme and a 3 turn helical for flying around trees and my wings when flying out 2-3 km. Works great on my SkyZone goggles...Also had good results swapping the helical for a VAS SkyHammer. Worst performance was with my Farview Pagoda and 3 turn helical on the SkyZone goggles although they work great on my Aomway V1 goggles. If you have both a SkyZone 03O and Aomway V1 can you compare the sensitivity of their receivers please?
I dont get too many FPV gogglges here... everything above a certain budget isnt easy to get access to as a reviewer if you dont sell 1000s of units for the onlineshops. I was about to get the Aomway commander V1s (as they were really cheap around 180$) but apperantly they're out of stock now and will not be produced? but anyhow, currently my curiosity in FPV tends towards DJI hd. Awesome experience. Dont wanna wear anything lower than a good fatshark with Rapidfire after DJI stuff. And as I said, not even sure if I wanna go analog at all anymore :)
Is there a better antenna than Aomway cloverleaf? They seem to be hard to beat. I have my antenna mounted about 35 ft off the ground . I need a good long range antenna with 360° reception. I will not be flying above 400 ft. Are right above my ground station. . giving you a hint of the radiation pattern I am looking for. With My 4 leaf Aomway antenna on my RX and TX and 600 w transmitter I have been out to 1.80 MI. at that distance reception is snowy but still visible. I don't want to use a patch on my receiver cuz for one thing it's 35 ft in the air and too hard to change when I want to fly in a different directions. Thanks for any of your advice..
@@kaelstokes5804 well it's been a year since this message I have now been out 2.9 miles with my aomway cloverleaf antenna. I'm just going to stay with them since it works for what I m doing.
RCSchim I see. I do this same type of test when I build antennas for myself. It works really well. I bought the AAI Vector impedance analyzer a while back also. It’s a great tool to have.
Great vid as always. I’ve fallen down the dji rabbit hole too. Have spent a fortune on antenna, the only ones that make a noticeable difference are patch’s. The TrueRC/axii2 are no better and in many cases worse than dji own.
thanks for this kind of feedback - helps me decide which way to upgrade my DJI experience. Quad shield? or 4 helicals as someone suggested? I dont know yet...
@@Rcschim I'm running Truerc stubby on my goggles for the sole reason they fit in my bag without removing them. I have the truerc dual patchs for dji which I tested also. While they have better range their penetration in the woods I fly is only slightly better than omnis so I rarely bother I haven't noticed any major difference on the quad between axii 2 lollipop 3 or the stock dji. Also they are so barely polarised that it doesn't seem to make any difference if you use rhcp with lhcp.. . Looking forward to your video :)
So just to be clear, other than the Helix spirals, there seems to be no point in using anything other than a standard antenna to average reception flying 360 degrees around the transmitter?
You can make a dummy load with a 50ohm resistor. Hooking an antenna to it wont be exactly 50ohm and will vary as you move things near it or if metal is nearby. It will also, being an antenna, radiate the energy that you don't want radiated. That dummy load is for absorbing energy received in the other polarization which could come from a different polarized antenna or from a reflected signal from your vtx which could interfere with the signal coming directly. A reflected circularly polarized signal swaps polarity. The antenna will work fine without the dummy load, but not optimally.
Nice tests Mario, funny I watched this just to see performance for my DJI goggles, and you mention it at the end :) looking fwd to your tests. I use 4 on goggles with mmcx lollipops on quads, but have 2 VAS crosshair extremes for the top ports, but rarely need. Check out my range tests vids I superview dvr, works great.
@@Rcschim yes top 2 send & receive bottom 2 receive only ..per Hugo truerc few guys using the ORT shield on the Facebook group already with good success. And did ya know dji limited the goggle output with stock antennas by 50% to meet FCC Regulations ; ) & Im sure ya know about the 1 watt & 1 200mW hack it's all over youtube
@@flo-ridafpv5713 I need some rpsma to sma adaptor connectors - seems I only have the other way round. I would have a lot of antennas that can fit there niceley. I read - they chose rpsma and lhcp on purpose, so they are more off standard - and than other regulations are to be applied? however, it would have been too easy if they are just rhcp and sma. lhcp - being used not so often is a good idea however... yep, I know about naco and his stronger brother "naco-power" ;)
@@Rcschim yes correct they did thst also to skirt regulations as rpsma is non standard but as you know also superior for wear, got mine on amazon & never remove them. Hey another tip, Sander sassen pointed out in the official facebook group DO NOT OVERTIGHTEN aftermarket adapters or antennas as this twists the coax inside and leads to internal breaks & bad signal. He's dji fan boy now lol #nacolife
@@Rcschim did you also know that digital MIMO uses multipath bounces to get better signal ? Make sure to test yours in concrete steel areas OK you'll love it... I can fly behind many buildings now w perfect signal, watch my flight called BRICKS and STEEL...amazing a true game changer I luv DJI
The ORT Micro DUAL Shield Antenna Module is not very good for my Freestyle locations. I found reception a big let down vs my Omni VAS Ion and Lumenier Patch on the Rapidfire. Sending the ORT back.... however, the form factor is fantastic. It just does not work for me...I sure wish it did. RC Schim..... awesome review as usual. Always great info. Thanks.
Thanks for the feedback. I tried it on a few occasions. But truth is: with higher mw on these coptesr - you get away with most antennas. with low mw - it's then to scary to fly - unless the antenna really delivers. I'd need a GPS save copter to do these kinds of tests (as I tried a few weeks ago). from the numbers, the shields dont look stellar. maybe a 3turn helix is better choice? and a long cable omni as a 2nd antenna...
Standard Linear Antenna is the best?!?!? i struggle to understand the results...is the minimum of the two columns the best antenna? if so the Standard Linear Antenna is very good
the values suggest - and it's true - with a Linear you get the best signal IF THE PLACEMENT IS OPTIMAL. But if you pan or tilt your copter/plane or if you fly near reflecting objects you get BAD signal interference (multipathing) - and that's where the CIRCULAR Polarized antennas are much better... So for a non moving application - linear antennas are still better (like on my WIFI routers)
i cant understand how those numbers work so i’ll ask which patch is better spironet or the ort dual shield and whats a better omni ort pagoda or lollipop v3?
hey, Spiro Patch is better in one direction, dual shield is better for convenience (you get pretty wide angle of medium good gain); ORT pagoda would be more range, but not a perfect round sphere but rather a flatter dounut. so more range horizontal, less above you... hope this helps
@@Rcschim Ich glaube die sind sehr gut. Hab ein Video gesehen wo einer damit 7km reisst...sowas geht normal nur mit ner Helical. Welchen VTX kannst Du empfehlen für Longrange? Grösse ist egal es soll in ein Flächenmodell.
12:32 How can this give you 180 ° Beam when they are not in an 90° Angle to each other? They are on 30° to each other. This means they overlap 60° to each other. And this means you will have a beam width of around 120° ! Not 180°!!!!
I guess you're right here :) So let's just say: they have a wide enough beam to see almost everything infront of you... beamwidth specs are to be taken with a grain of salt anyways. they are for a specific db gain (most times for a low gain number). On the higher gain (the max gain of the dir. antennas) they mostly have narrower beams. So the beams are not cones which extend into eternity, but rather oval shapes...
That's the numbers - and it makes sense. But I don't know how this scales with distance. Here in my tests I have little RF power and little distance. If you fly with normal powerlevels and have >1km distance - maybe it would look differently...
Hey man, can u please help me out? I have the eachine ev800d, it comes with a omni 5dbi, recentely, i bought the lolipop3, 2.5dbi omni as well. So if i put this on my googles i would have a worse result?? Or am i right to think that with a lolipop ill have worse range but better image quality instead of that omni from eachine??
hey, I'm quite sure, that any antenna will be better than the eachine antenna ;) Lollipos are pretty good. Even better whilst cheap: Aomway SPW antennas for omnis. greets, Mario
@@Rcschim thanks for your quick reply Mario. Even if im flying planes, like 600-1000m away, in theory, the Eachine clover leaf has way more dbi, almost twice. Even consdering that, the lolipop is a better option?
I seriously doubt the eachine clover antenna has actually 5dbi! look at this from ORT, it's also 6 lobe (slightly different design, but really good antenna builder!) and they say it's 1.5-1.7dbi! oldradiotransmission.com/product/ort-goggles-edition-antenna-5-8ghz-violet/ 5db is already a directional antenna (or a very "flat" donut shaped omni where you have good 360 horizontal, but very limited in vertical). So again, I can only suggest know good antennas like the aomway spws, or immersionRC spw, or maybe the pagodas (they have a bit more horiz range - they are also a bit "flatter" from the RF pattern... greets, Mario
@@Rcschim yeah Mario, thats for sure, i really doubt from this specs of China companys. Anyway, thanks for all the advice. Ill make some field tests and see what i can found about it 😁
Good effort, but your tests are a bit skewed. The 5.8Ghz band is pretty wide, so an antenna performing bad on R1 5653MHz might perform excellent on R8 5933MHz if it is tuned for lowest SWR there.
Totally agreed. As I said before - wish I had the time to do these test in all variations and condense really solid information. I can only aim for this goal :) For the average FPVer fatshark 4 should be a good "middleground" dont you think?

I've wanted to see something like this for a long time. Thank you so much for spending the time and money to gather these results :)
Can't get enough of these, hope there's more :)
Just reading the video title and knowing the previous 2018 episode: This will be great!
Thanks. I love doing such videos, but sometimes I wish I had way more time for them...
Missing: TrueRC X-Air and Lumineer Axii 2
Thank you for finally doing an updated video! Many have done it a long while ago and left it to rot!
I seem to have to same issue as you have: mostly "outaTime". But here I forced myself to spend this hour up their and I'm so happy that I could finally do this 2nd test. I learned a few things again - and my next test will be better. Probbably not before spring tho :)
That's a lot of antennas, i appreciate the video index in the video description but i think you should also post it in the comment section and pin that comment ;)
Have a great weekend Mario and keep it up the great job
Thank's Cedric, good idea.
Btw: I found out, I can export text markers from my Vegas timeline in text format and paste them here. Wish I knew this earlier ;)
Awesome testing, Mario! Really nice! 😃
Thanks a lot!
RCSchims that was a Great Video & You put Quite a bit of Work & Time explaining it ! Great job ! You always have Nice Videos ! Thanks !
Thanks for the awesome comparison video! I'm using the Menace Pico and its been solid. I'm really impressed with those helicals you showed.
me too. I only used helicals on my groundstation - because the 8turn are kinda big... but the 3.5turn is good I guess!
One of the best antennas tests
A big THANK YOU and hats off to Mario !!
Just to be picky ... given the power increase ratio (~1.26) from tests beginning to end, 1 dB should be added in absolute value to the final results .... isn't it ?
this time I didnt chech the power output of the TX.
But also: this time it was ~7°C and windy - so maybe the TX was cooled enough to have a quite constant output.
On the bench I found a good correlation between heat and degradiation of RF power. But it took 40 or 50°C to see a decrease of RF power...
Thank you for all the data! It’s gold versus perceptions and opinions!
Nice! Exactly what i was looking for. Thank you for all the effort you put into it.
Nice to see such positive feedback right away. I guess this is of interest for most FPVers - since a lot of times we have to guess which antennas are really as good as advertised...
rf stuff is difficult :)
Awesome antenna video i love that i have no doubt which with what i use and it because of your detailed reviews
wow you're the mvp of antenna reviews. why is nobody else doing this testing? I find it quite curious that the latest lollipop antennae seem to do worse, any idea why? or are there other factors making them better in practice?
hi, thanks. the newer (back then) lollis were just made cheaper - that's why their performance dropped.
Newer products are not always an improvement (of course marketing always suggests this) sometimes they are just cheaper to make.
Of like with the DJI cams: because some chips are not available - other ones have to be used (but those other cams are not as good as the OG DJI cams :)
Would be good to see more of these for analogue :-)
exactly was I was looking for, thanks for the work!
Many thanks for yet another antenna review, best in the business, cheers!
Thanks alot!
Seven hundred and seventy third! 😀 Another great set of tests, mario 👍
i'm still using the aomways on my quad and the stock antenna on the ev800d, they work really well , better than using two aomways........
Would love to see ProDrone antennas in with the test, but great job done
Yea, I think the french guy, RedBaron did test those antennas. Do you know his tests? Forgot his name, but search RedBaron and antennatest - he has a nice series...
@@Rcschim many thanks, but would his tests be as real world as yours?
Ahhh yes I have seen those tests, and good test too
@@mikeellicott6977 for sure - they are in fact way more "real life" than my test here! check it out here: ua-cam.com/video/eWlLO6QqxGg/v-deo.html

Nice review. I am using VAS ION V2 & TrueRC X-Air on my goggle and O.R.T Pagoda V2 for my quad. This is the best setup in my flying area.
Nice thorough job as always my friend!
Thanks!
Excellent consistent list, I can find an optimal antenna in a few seconds! You should do propeller--motor thrust tests. MiniQuadTestBench still doesn't use Gemfan Hulkie 5055 or Flash 6042 in any tests. You'd rock at filling the gaps there.
Thanks for the tip. Any excuse to buy another measurement device is welcome ;)
When it comes to props I don't know much yet. Mostly fly the same dalprops since foxeer sent me many of them..
Первый нормальный тест на весь ютуб! Молодец
ORT antennas is the best😍
Love my dji!!! Cant wait for your antenna tests!!!
Already enjoying the last couple of days in the sun in nz
Excellent analysis. Thanks Schim
Love your testing! Can I advise a small tweak to your testing methodology that will help give you larger # spreads on your omni’s and truely show which are better? Space your RX at a larger distance to the point where the worst antenna of your batch is showing 81-82 in the null zone, rather than no antenna in the null zone distance. This greater separation (might be 10m+) will give you much more accurate and easily rateable rankings for which antennas are truly better than the others. Thanks again Schim!!
I agree. That's what I meant, I'd like to have way more time for such test session...
For your suggestion I need to know which antenna is the worst performer and set the distance according to this. Maybe I should make 2 groups: omnis at closer range and directional antennas in their own class where the distance is a few hundret meters (even when using only 1mw transmit power).
thanks for the feedback - I like the challenge :)
Totally!! That’s exactly what I would do. Max-our your poorest omni for range @ 81db and then run all your omni tests from that point. Then have a second test group just for directional antennas at a range that also maxes out the “worst” directional antenna @ 1mW.
Great testing Shim! I wish I had some extra Axii 2 & Axii micros to send you to test alongside those lollipops as it’s interesting how every revision of lollipop appears to have slightly worse range. Haha. For omni’s my personal favorite on the goggles are the pagoda 2 (open air) and the VAS Ion/Minion. For patches the TrueRC Air2 (pepperbox) for the performance and the menaceRC patches for their size.
Thanks again Shim! Love your videos & testing!

thanks SOOOOO much for that :-) I was looking for a good patch and you did the job for me. I now know what to buy :-)
And what did you choose?
Great review always, I wish you could review the True Rc singularity.
Nice!
For next round, Orqa FPV.P1.Pro & FPV.O1.Pro?
Also, TrueRC Singularity stubby & long? :)
thanks for suggestions. always nice to see what you guys use. Orqa goggles? there's quite a hype about them right now, right? I didnt even check their specs. Will do my homework soon :)
@@Rcschim yeah, I received my Orqa goggles last Monday (tl;dr: awesome & evolving quickly) with the pro antennas, so was wondering how well they performed in various scenarios 😅
Vielen Dank für das interessante Video.
schöner test :) sehr informativ und übersichtlich 👍
Leider vermisse ich ein wenig die Antennenfreund.de Antennen. Handgeschmiedet in Deutschland ;)
Ja, aber geschmiedete Antennen klingen doch viel zu schwer für unsere kleinen Copter :)
Ich geb zu - ich hab hier für den Test einfach die Antennen genommen, welche ich so gesammelt hab. Versuchte schon ein paar Hersteller anzuschreiben, bekam aber ausser von Banggood und ORT keine Review-Samples. Und alle möglichen Antennen selbst zu kaufen, dafür reicht das UA-cam-money leider bei weitem nicht :)
Super! Vielen Dank für deinen Test 👍👍👍
Bitte gern, war interessant zu sehen, wie die einzelnen, doch recht gleichen Antennen untereinander abschneiden und hilft mir selbst auch, zu entscheiden, welche Antennen jetzt auf die Fatshark drauf kommen (oder später dann auf die DJI)
Nice video mate, I look forward to the DJI review. :-) I'm sure you will be trying them with different antenna's :-)
I will - which reminds me that I need to order some RPSMA adaptors now!
Ty,exactly whatvIbwas looking for. Real measurments and numbers, good work 🛰️📊👍 I spend all my money for my first diy-drone & all the rest, but when I have some over I send you some antennas to test. Good to know if cheap Chinaantennas are a good alternative
Excellent video as always ..
After thoroughly studying your excellent Excel spreadsheet, it is kind of amazing that none of the omni antenna's are really any different in performance from one another! Sure, the old blue Aomway gets a score of -58, but none of the others are much worse than -60 !! I guess the ORT 6Lobe SPW is slightly better, but not enough to pay it's price since I have a perfectly good blue Aomway.
I find the difference between any of the omni's to be pretty insignificant, don't you think? (except for the Thor and some other old ball ones that aren't that popular).
I also found it weird that the further we get into the Foxeer lollipop line, 1, 2, and 3...the WORSE they get! Course the best is the first one, and you can't buy it anywhere! lol D'oh!
I think I'll stick with the blue Aomway and the Triple Feed Patch 9.4dB on the other side. That one appears to be the BEST BUY of any of these, at under 11 bucks!
Great Review my friend! Thanks for all of your time and efforts!!! =(:^)-
Bravissimo, as usual :) thank you!
Thanks
@@Rcschim Prego
Good video thank u this is an important video to me and I guess to everyone else who wants to get good reception flying.
Great that I found ur video like it I learn more thank u.
Oh man those ORT Helicals are expensive! I would have loved to see the triple feed patch array, maybe in 2020 ;)
I remeber that I paid 64€ for the circular wireless antennas back a few years ago. and even this money wasnt wasted - they gave me good confidence while flying further out an expensive model...
And: as alisdair... commented: it's really hard work to make a well tuned helical - not easy to make them in large number with good quality. they need to be hand- tuned to work that well...
The only problem in this test is that it is done for 1 frequency only. the 5.8ghz band is pretty wide. A well tuned antenna on it's center freq, can give way more gains than a wide band antenna. A well tuned antenna but used at the wrong frequency, than were it is tuned for could perform bad, while it can be a great antenna. So if you want to to get the best antenna, buy a custom tuned antenna for your frequency. The custom tuning and measuring and small tolerances is what good antennas makes expensive.
Also because tolerances are very small, it is also questionable if factory made generic untuned antennas are peaking at the same frequency, or if there can be significant differences between different antennas.
good point, kinda hard for me to test all the antennas at many different channels. But I agree - THAT would be a thorough test :)
Thanks man. You answer all my question which the best antenna for my setup. Ort look good for me
It would be interesting to see results from the ORCA PATCH
yep, and if they are not to be sold seperatly from the goggles - i'd take the goggles as well and would take a look at them :)
Seriously: I'll try to get more antennas over the next weeks and test more...
I bought their promotional video patch a while ago when they first came on the scene, they claimed a good performance, I use it all the time but I only have a few patches inc the crappy aomaway patch that came with goggles so have no real comparison, looking forward to you additional reviews in due course, I’m really wondering whether to go ORCA or DJI now, saving up so still have time, keep up the good work, I really enjoy your tube.
@@wezcrutchfield It's a tough descision. I dont know if DJI will superseed all my analog video gear already. atm I'm all on DJI and dont wanna fly analog. But on a nice sunny day, enough batteries and my trusty little freestyle SpeedyBee - I could fall for the simple analog video again.
Bardwells goggles Review was good - but even he struggled to give a definitive recommendation... The Orqua with wifi and future proof cpu power and everything - they for sure go a different path than the isolated DJI fpv system. If DJI succeeds - it's ok and all we need... only time will tell - most important thing: have fun in the air! greets, Mario
Got all excited when I saw a couple of omni's I have lurking in your basket. Not tested here through................................
If I didn't test all of them check my 2018 test, it is linked at the end...
ORT IS BADASS.!!! BEAT EVERYTHING!!👍👍👍
Awesome infos thanks !
Well... It's still spring here... And it has been raining for weeks! 😭
you have to see the positive sides Mario: if it rains, this normally means your surrounding nature is lush of green plants rather then a desert, right? :) wish you a nice weather spring soon tho!
@@Rcschim Yeah, you're right about that! And thanks! 😊
What about sma to bnc antenna with high gain range?? THKS
Hi, great test, well done, I found this very interesting and like your method, thank you for sharing this :-)

Cheers Guys
super clear thankyou!
ORT made from my country.. populer and very good durably... thank you Mr RCSchim for awesome review ...
Great job! Thumbs up!!
Great work, thxxx 💚🍀💚
So according to your test results which omni-directional antennas are the most suitable for high power long range ?
A lot of pilots use 90 degree connectors and even less use 45 degree or straight out of googles. Can you talk about amount of loss from different angle connectors?
Fairly sure IBCrazy did a test and found a very small loss
It's around 1dbi loss.
I'd really like to get an opinion on the difference between the Dual Shield versus the TrueRC MX-Air Array. The MX-Air have less power but are double the price and four times as big as the Dual Shield... TrueRC builds quality stuff though.
No luminier axii?
I'll try to get some for my next video (which is actually planned to shoot soon). but currently I have to by most antennas myself. except foxeer (but they arent always good) or other stuff I can get from banggood...
still have a lot of antennas in my antenna-bag to test :)
@@Rcschim thanks new sub
Next to test idea: truerc sniper v2 patch, mx air, x² air, singularity, vas minion, vas sky hammer
I'll add: any and all VAS incl patches, tbs triumph pro, menace invader, and more micros; iflight Sigma,
truerc singularity, emax nano
Same love my sky hammer 👍
I suggest you not spin the whole antenna when you put them on. It's destroying the stinger and especially stinger receiver. Insert the antenna, then twist the outside nut so to not damage the antennas. Anyways thanks for the review.
Thanks for the tip!
I fly but don't understand antenna specs. Based on this list, what would be an optimal set up for flying in slightly wooded areas with a few trees. Some may be thick with a lot of leaves while others would have a lot of dry branches. I use an IRC Omni and IRC patch on the goggles, with an IRC Tramp vtx with a Foxeer Lollipop antenna. Sometimes the video breakup can be crazy. As long as I keep the quad in front of me, most of the time the video is fine. Also, I'm not using a capacitor if that means anything.
do you use RapidFire on your goggles? that could help alot :)
also if you do: make sure RapidFire is calibrated (mine wasnt and my breakup was worse than it should have been).
IRC omni could be swapped for example to this Foxeer Pagoda pro on the long cable - it was quite good from the numbers.
IRC 8dbi patch is pretty good - not sure if another patch would give you better results.
maybe consider the 3turn ORT helix - it looked really good!
@@Rcschim No, I use the La Forge diversity module. However, I'll look into Foxeer Pagoda. I was also considering the Luminier AXii Omni and their patch with a matching omni on the quad. The one on the goggles would have an extended cable. The helix may be an option for the patch. I may have to try combinations with a higher output to see what gets me the least breakup.
Just can't keep your mouth shut about the DJI. :D It's just that good. NOT hype folks!
When comparing the helicals, you state that the 6 turn isn't that much better than the 3 turn. However, there is 4db of difference. That's actually quite huge since 3db is double. I know you'd probably get hazed for doing it, but it might be helpful to throw all of the numbers in a db-to-mw converter just so you can see them on a linear scale.
In one of the VAS videos, he talks about the shape of the helical polarization not being as circular as he'd like. So I'm wondering if the VAS antennas may excel in a more noisy environment, whereas the helicals are better at long range where you generally keep line-of-sight.
I definitely want to try the ORT 3 turns through heavy trees. But with DJI,.. I need 4 of them,. so it will have to be when I have money burning a hole in my pocket. Right now I'm running VAS SkyHammers.
Thanks for your feedback - db to mw in a seperate column in XLS sheet - good Idea - will do.
Good points about that few db - sometimes we tend to forget this...
The thing is: RF theory and it's practical application are extremly complex with so many factors. Tests like this here always have to be extremly oversimplified - and only pick one aspect of the antenna.
I'm quite sure that the VAS antenna HAS TO BE good. I just didnt use it in a way yet so it would convince me :) So for guys like me - the allround antennas are for sure better...
Not sure if I want 4 helicals on that DJI goggles - it makes you look damn stupid again - whereas the current stock antennas look kinda cool :)
@@Rcschim Haha,.... embrace the geekiness! I'll admit, 4 helicals on the goggles does give me pause. But I've also used the VAS cyclops,.....which is extremely ugly.
So yeah, I have a fairly decent collection of VAS antennas. My thoughts are that the patches are only slightly above average, but the omnis seem to be quite good. I'm currently running 4 SkyHammer's on the goggles, and 2 Minion Pro's on the quad. This setup seems to keep me locked at 25Mbit's for 95% of my flight paths. It's not long distance though. Just lots of obstacles.
The stock antennas do seem to do quite well if you're not really pushing the limits, which we don't most of the time. One thing several of us found, was that the stock antennas are barely circular polarized. We've switched out the quad antennas for RHCP, and left the stock antennas on the goggle, and there is no difference. Some think the stock antennas are better than many of the omnis, but my testing with aftermarket omnis shows a definite improvement.
hello from germany. Nice video
gracias
would have been nice to see a VAS crosshair extreme, and a skyhammer
o damn -- theres the crosshair extreme :P -- but still wish there was a skyhammer
RC Shim....I have been using a VAS crosshair extreme and a 3 turn helical for flying around trees and my wings when flying out 2-3 km. Works great on my SkyZone goggles...Also had good results swapping the helical for a VAS SkyHammer. Worst performance was with my Farview Pagoda and 3 turn helical on the SkyZone goggles although they work great on my Aomway V1 goggles. If you have both a SkyZone 03O and Aomway V1 can you compare the sensitivity of their receivers please?
Btw I use a 3 turn Hyperion helical with a reflector at the end.
I dont get too many FPV gogglges here... everything above a certain budget isnt easy to get access to as a reviewer if you dont sell 1000s of units for the onlineshops. I was about to get the Aomway commander V1s (as they were really cheap around 180$) but apperantly they're out of stock now and will not be produced?
but anyhow, currently my curiosity in FPV tends towards DJI hd. Awesome experience. Dont wanna wear anything lower than a good fatshark with Rapidfire after DJI stuff.
And as I said, not even sure if I wanna go analog at all anymore :)
@@Rcschim feel like the swan song now for analog. But I need the size of the air unit to decrease.
suggest antenna for the next shootout....Rush Cherry Antenna
Thanks, I'll take a look - but they look pretty similar than the Foxeer Lollipop.
Great work..Subbed!
Is there a better antenna than Aomway cloverleaf? They seem to be hard to beat. I have my antenna mounted about 35 ft off the ground . I need a good long range antenna with 360° reception. I will not be flying above 400 ft. Are right above my ground station. . giving you a hint of the radiation pattern I am looking for. With My 4 leaf Aomway antenna on my RX and TX and 600 w transmitter I have been out to 1.80 MI. at that distance reception is snowy but still visible. I don't want to use a patch on my receiver cuz for one thing it's 35 ft in the air and too hard to change when I want to fly in a different directions. Thanks for any of your advice..
Use a 3 or 5 turn helical, they have good gain and wider beam than patches. Use a diversity RX and 2 helicals to get even better coverage.
1.8 miles on omni antennas is insane!
I know u busy but I have a quick question which antenna is better the Foxeer Pagoda Pro antenna lumenier axii 2 Or the foxeer lollipop 3?
@@kaelstokes5804 well it's been a year since this message I have now been out 2.9 miles with my aomway cloverleaf antenna. I'm just going to stay with them since it works for what I m doing.
Why no antennenfreund?
maybe next round?
It's actually a higher number if the lower number is a negative. Good video though. Thank you.
I know, sometimes I keep it simple to make them videos more accessible ;)
RCSchim I see. I do this same type of test when I build antennas for myself. It works really well. I bought the AAI Vector impedance analyzer a while back also. It’s a great tool to have.
Please test TBS patch sometime.
Great vid as always. I’ve fallen down the dji rabbit hole too. Have spent a fortune on antenna, the only ones that make a noticeable difference are patch’s. The TrueRC/axii2 are no better and in many cases worse than dji own.
thanks for this kind of feedback - helps me decide which way to upgrade my DJI experience.
Quad shield? or 4 helicals as someone suggested? I dont know yet...
@@Rcschim I'm running Truerc stubby on my goggles for the sole reason they fit in my bag without removing them. I have the truerc dual patchs for dji which I tested also. While they have better range their penetration in the woods I fly is only slightly better than omnis so I rarely bother I haven't noticed any major difference on the quad between axii 2 lollipop 3 or the stock dji. Also they are so barely polarised that it doesn't seem to make any difference if you use rhcp with lhcp.. . Looking forward to your video :)
So just to be clear, other than the Helix spirals, there seems to be no point in using anything other than a standard antenna to average reception flying 360 degrees around the transmitter?
so what is the farthest antenna? Or what is the most recommended? :) #StayAtHome
Ha, today I will do another one of these videos actually.
Currently id say: a good helical for long range, a lollipop for omni directional.
Can I use a 50 ohm antenna as the dummy load on the triple feed patch? 50 ohms of impedance is 50 ohms right?
You can make a dummy load with a 50ohm resistor. Hooking an antenna to it wont be exactly 50ohm and will vary as you move things near it or if metal is nearby. It will also, being an antenna, radiate the energy that you don't want radiated. That dummy load is for absorbing energy received in the other polarization which could come from a different polarized antenna or from a reflected signal from your vtx which could interfere with the signal coming directly. A reflected circularly polarized signal swaps polarity. The antenna will work fine without the dummy load, but not optimally.
Nice tests Mario, funny I watched this just to see performance for my DJI goggles, and you mention it at the end :) looking fwd to your tests. I use 4 on goggles with mmcx lollipops on quads, but have 2 VAS crosshair extremes for the top ports, but rarely need. Check out my range tests vids I superview dvr, works great.
About dji: is it known already, which of those 4 antennas are tx and which rx?
Eko (ort) also has a quad shield, maybe they want a review? ;)
@@Rcschim yes top 2 send & receive bottom 2 receive only ..per Hugo truerc few guys using the ORT shield on the Facebook group already with good success. And did ya know dji limited the goggle output with stock antennas by 50% to meet FCC Regulations ; ) & Im sure ya know about the 1 watt & 1 200mW hack it's all over youtube
@@flo-ridafpv5713 I need some rpsma to sma adaptor connectors - seems I only have the other way round. I would have a lot of antennas that can fit there niceley.
I read - they chose rpsma and lhcp on purpose, so they are more off standard - and than other regulations are to be applied? however, it would have been too easy if they are just rhcp and sma.
lhcp - being used not so often is a good idea however...
yep, I know about naco and his stronger brother "naco-power" ;)
@@Rcschim yes correct they did thst also to skirt regulations as rpsma is non standard but as you know also superior for wear, got mine on amazon & never remove them. Hey another tip, Sander sassen pointed out in the official facebook group DO NOT OVERTIGHTEN aftermarket adapters or antennas as this twists the coax inside and leads to internal breaks & bad signal. He's dji fan boy now lol #nacolife
@@Rcschim did you also know that digital MIMO uses multipath bounces to get better signal ? Make sure to test yours in concrete steel areas OK you'll love it... I can fly behind many buildings now w perfect signal, watch my flight called BRICKS and STEEL...amazing a true game changer I luv DJI
The ORT Micro DUAL Shield Antenna Module is not very good for my Freestyle locations. I found reception a big let down vs my Omni VAS Ion and Lumenier Patch on the Rapidfire. Sending the ORT back.... however, the form factor is fantastic. It just does not work for me...I sure wish it did. RC Schim..... awesome review as usual. Always great info. Thanks.
Thanks for the feedback. I tried it on a few occasions. But truth is: with higher mw on these coptesr - you get away with most antennas. with low mw - it's then to scary to fly - unless the antenna really delivers.
I'd need a GPS save copter to do these kinds of tests (as I tried a few weeks ago).
from the numbers, the shields dont look stellar. maybe a 3turn helix is better choice? and a long cable omni as a 2nd antenna...
Where are you from bro ?
Austria
Standard Linear Antenna is the best?!?!? i struggle to understand the results...is the minimum of the two columns the best antenna? if so the Standard Linear Antenna is very good
the values suggest - and it's true - with a Linear you get the best signal IF THE PLACEMENT IS OPTIMAL.
But if you pan or tilt your copter/plane or if you fly near reflecting objects you get BAD signal interference (multipathing) - and that's where the CIRCULAR Polarized antennas are much better...
So for a non moving application - linear antennas are still better (like on my WIFI routers)
RCSchim ok got it
i cant understand how those numbers work so i’ll ask which patch is better spironet or the ort dual shield and whats a better omni ort pagoda or lollipop v3?
hey, Spiro Patch is better in one direction, dual shield is better for convenience (you get pretty wide angle of medium good gain);
ORT pagoda would be more range, but not a perfect round sphere but rather a flatter dounut. so more range horizontal, less above you...
hope this helps
Hey hast Du mal die True Rc X2 Air getestet?
Hi! Nein, aber die schaut schon recht gut aus. Leider ein wenig teuer. Auf der DJI FPV wird diese Antenne (im Doppelpack) ja auch sehr gehyped.
@@Rcschim Ich glaube die sind sehr gut. Hab ein Video gesehen wo einer damit 7km reisst...sowas geht normal nur mit ner Helical. Welchen VTX kannst Du empfehlen für Longrange? Grösse ist egal es soll in ein Flächenmodell.
12:32 How can this give you 180 ° Beam when they are not in an 90° Angle to each other?
They are on 30° to each other. This means they overlap 60° to each other. And this means you will have a beam width of around 120° ! Not 180°!!!!
I guess you're right here :) So let's just say: they have a wide enough beam to see almost everything infront of you... beamwidth specs are to be taken with a grain of salt anyways. they are for a specific db gain (most times for a low gain number). On the higher gain (the max gain of the dir. antennas) they mostly have narrower beams. So the beams are not cones which extend into eternity, but rather oval shapes...
@@Rcschim Joa, kann man wohl sagen. Aber 60° grad sind halt nich wenig aber ok.
ORT 6.5 turn helical gets -65dbm at 90 degrees? Holy sh*t that's as good as the IRC SpiroNet, are you sure that's correct?
That's the numbers - and it makes sense. But I don't know how this scales with distance. Here in my tests I have little RF power and little distance. If you fly with normal powerlevels and have >1km distance - maybe it would look differently...
Hey man, can u please help me out? I have the eachine ev800d, it comes with a omni 5dbi, recentely, i bought the lolipop3, 2.5dbi omni as well. So if i put this on my googles i would have a worse result?? Or am i right to think that with a lolipop ill have worse range but better image quality instead of that omni from eachine??
hey, I'm quite sure, that any antenna will be better than the eachine antenna ;) Lollipos are pretty good. Even better whilst cheap: Aomway SPW antennas for omnis. greets, Mario
@@Rcschim thanks for your quick reply Mario. Even if im flying planes, like 600-1000m away, in theory, the Eachine clover leaf has way more dbi, almost twice. Even consdering that, the lolipop is a better option?
I seriously doubt the eachine clover antenna has actually 5dbi! look at this from ORT, it's also 6 lobe (slightly different design, but really good antenna builder!) and they say it's 1.5-1.7dbi! oldradiotransmission.com/product/ort-goggles-edition-antenna-5-8ghz-violet/
5db is already a directional antenna (or a very "flat" donut shaped omni where you have good 360 horizontal, but very limited in vertical).
So again, I can only suggest know good antennas like the aomway spws, or immersionRC spw, or maybe the pagodas (they have a bit more horiz range - they are also a bit "flatter" from the RF pattern...
greets, Mario
@@Rcschim yeah Mario, thats for sure, i really doubt from this specs of China companys. Anyway, thanks for all the advice. Ill make some field tests and see what i can found about it 😁
👍👍👍👏👏👏
Good effort, but your tests are a bit skewed. The 5.8Ghz band is pretty wide, so an antenna performing bad on R1 5653MHz might perform excellent on R8 5933MHz if it is tuned for lowest SWR there.
Totally agreed. As I said before - wish I had the time to do these test in all variations and condense really solid information. I can only aim for this goal :)
For the average FPVer fatshark 4 should be a good "middleground" dont you think?
+3dB is doubling of amplitude!

Antennae 😜
Guess you're right, but it was long unnoticed ;)
Those menace antenas are overrated like whole company.
