is the banggood link what you intended? for me its only offering the full kit goggles air and radio... i had assumed this was the goggles and 2 air unit link
@@TheMadmacs yes looks like they are out of the two air unit deal but its still a £200 saving if i were to buy from a shop in the UK
@@AndyRCchannel yeah even banggood price was higher before they ran out of 2 air unit deal, this is basically a free radio.
@@TheMadmacs you got it! and the radio can now be used with a sim
AndyRC I am totally new at this, Titan DC5 waiting to be flown, flying in all the available sims, looking forward to use my goggles with the sim and with my TinyHawk, before I attempt to crash my Titan. Very interested to know how to use the goggles with the sim now. What changed? And also, what is the cheapest decent Fatshark receiver module just so I can FPV my TinyHawk, don’t want to spend much as I will be focusing on digital, but don’t want to buy separate goggles just for the training phase on my TinyHawk. Hope you can shed some light. Excellent video BTW, glad to be a subscriber!
Just want to say....... What a fantastic, well researched, professionally presented video.
Very impressed.
thanks for watching and commenting. Cheers
I own the system but didn't know any of that. Thanks so much for all the information and recommendations. Your videos are a treasure for the community.
Hey Andy I'm writing just to say that, as someone new to this hobby, I'm watching a lot of videos from a lot of different people about fpv. Most of the most viewed channels are annoying and full of unuseful banter. You are by far the most informative and your videos highlight the real pros and cons of what you're reviewing, while keeping it "professional" and clean. Thank you for the hard work !
thanks for the feedback much appreciated. cheers
This had way more info than the title was leading me to believe. GREAT STUFF!
This is what I was looking for. Background information without the whole analog vs. digital chatter. Thank you so much!
best explanation i have watched for dji antenna system.
Too funny. This afternoon, I went inside after a half pack, and shelved my black X Air, and two stubbies, swapping the stock antennas back onto my goggles. i was just tired of the funky mess pointing around, and the totally questionable/inconsistent gains I had experienced. Top channel, Andy. Thanks for the quality information.
u got it. Cheers thanks for watching
Very happy that Caddx has come out with their own module. Gives me another reason to hold off and wait for either a smaller module unit or a runcam/foxeer version. kicking the can down the road ftw!
yes pretty exciting. Hoping there wont be range issues with the single antenna. We shall have to see
Nice work. This is exactly the reason RP-SMA was developed for wi-fi routers to comply with government regs and make it hard for the end user to swap transmitting antennas.
On that note, Andy, I totally agree with you, let us get rid of silly regulations and enjoy the flying more as anything. Thanks for learning me something today.
I just bought the DJI FPV System along with an Air Unit and a Caddx Vista. I'm excited about this tech because I am a filmmaker. I have owned multiple DJI UAS that provide a great live image in stabilized flight or in hover, but as incredible as DJI systems have been, they have always lacked the ability to fly a camera the way that FPV Freestyle and Racing pilots fly theirs. Unless they are working on a production with large budgets, or have healthy resources to fund their pursuits, most FPV pilots haven't had an accessible system available that provided a reliable and robust digital signal to the pilot, and met all of the other technical requirements for various lightweight unmanned aerial systems. A massive and growing community of pilots will be benefiting from this technology, and even with the inevitability of whatever trade-offs must be made, this is already a pretty big winner. This system has been a long time coming, and will be part of a new era moving cameras through space. The master pilots that haven't gotten too many views on their old analog DVR FPV clips will now be able to blow your mind.
From the back woods to the back lots, this system is going to make some DPs into heroes, because they hired that kid down the street to shoot the Audi commercial, and the kid's been practicing with the DJI system, so he can get the shot in one take. :)
Putting a live camera into the action of FPV Freestyle, Cinewhoop, FPV Racing, X-Class and other sports that we're seeing emerge requires systems like this to enable broad and universal exposure. An analog FPV signal is typically not what a broadcaster is looking for from an event, and GoPro footage is great, but can be expensive or problematic to capture live from something as light and nimble an acro drone. Production companies have built compact FPV drone systems that are equipped for live broadcast for use in filming motorsports and other events in Europe, but some of those drones cost in excess of $10,000 when fully equipped to fly. That's in addition to the equipment in the OB truck and operators, which process and broadcasts the signals, and the team that both flies and supports the fleet of drones. A single event can involve two producers, four camera operators, two editors, two graphic artists, three pilots, and three flight crew, or many, many more.
These products are starting to change that. For the little guys, the big, guys, and everyone in between. Even if you're flying a bigger camera this system can be used to confirm shots, etc. The signal is very robust, and the image is fine as a live view monitor. Since this has extremely low latency you could use it to direct the camera, then use a Teradek or Connex with higher latency to get the main camera image.
Have fun! I'll be busy for a bit as I plan all the fun I'm going to have with the DJI FPV System at the race track, and Pikes Peak, and the reservoir... Yeeeee Haaaaw!
Now I get to put together some of my analog quads and radios to give to friends that want to try it out! That's a nice side benefit to adopting a new platform...gifts to friends. It's why I never really sell anything.
I was in a horrible car accident last Wednesday, so now my back is a bruised and strained mess currently and I have to take muscle relaxants at night, so I feel just a tiny bit loopy. That may explain the very impromptu DJI endorsement above.
(My wife read this and seems to think that I'm okay, and can't wait until I can get back out to fly my drones. She's very nice.)
Cheers, guys. I'm glad we had this talk.
Just got my dji finally.. and have to say.... you're a beast!... thank you for such video, well presented and very usefull., btw! hold on budy, things would get better soon!!! Keep up the great job Andy, you rock!
Glad someone is finally putting this stuff on a good video. I've commented on some of this, but of course, that doesn't spread the word as well as a good channel like yours. And while I agree that the stock antennas do a pretty awesome job, I think many antenna tests are flawed because they match aftermarket antennas on the goggles with stock antennas on the quad or the other way around. The stock DJI antennas seem to be barely circular polarized, which is why a linear antenna can work so well with them. So when you put aftermarket antennas on one device, but leave stock antennas on the other, you have a polarization mismatch and degraded performance, or at least degraded possibilities. In my testing, stock/stock does not perform as well as an aftermarket/aftermarket setup. Granted, I haven't tested a bando but my testing environment has some multi-pathing and penetration. I think for a bando, you want good omnis on both sides to catch the multi-pathing versus a patch which tries for penetration. What I have settled on for my type of flying is TrueRC Singularities on the goggles, and VAS Minon Pro on the quad. In my "bad spot", the stock setup dips into the teens for bitrate, but with the aftermarket, I don't get below 20Mbit. I originally bought the Singularties because they are compact. I didn't really expect much out of them performance wise, but was pleasantly surprised. They beat my testing of Lollipops, SkyHammers, Cyclops, and Pagodas.
I wouldn't doubt your meter readings so much. If you look, it is getting around 80% duty cycle on the quad side. If you consider the data flow, there is far more data going to the goggles. Most of what they are doing is acks. With it set on "peak", it is not considering the duty cycle. Also, your readings match the FCC testing. Their "Maximum Conducted Power" tests shows around 22dbm per connector, which is almost exactly what you were showing (160mw). I have done the same tests with the same meter. Some folks like to discount that meter because of JB's testing that had poorly performing pigtails. But when it matches the FCC testing,.... I believe that the power discrepancy is in DJI's "fuzzy math". In the FCC testing, they count the maximum power as two antennas added together since the system is MIMO. When you add antenna gain to 160mw and double it, it puts you pretty close to 700mw. Also, DJI's stated power in the FCC docs is slightly higher than the measured,.... which you would kinda expect them to undershoot actuals when talking to the government.
Since you have so much info on it, I assume you already have read the FCC testing, but for anyone who hasn't, google these.
goggle FCC ID ss3-p1gs1902
air unit FCC ID ss3-p1as1901
remote control FCC ID SS3-P1RC1901
Nice comment! Are you still using the singularities, did you try the Lumenier axII 2 setup?
I've done AXII's on the quad, but I never tried their goggle setup. Singularities are good enough for all of my current flying. I stay pegged on 25Mbit. I have Minion Pro on the quad.
Great video. Just got into the hobby and went the DJI route. Appreciate the advice!
I'm going for the Dji gear aswell, except the radio as not keen on the design of it. I've ordered the Jumper T18 Pro radio.
You my friend are a pro how could anyone give you a 👎 they clearly have no knowledge of our sport. Thanks so much and again I learned alot frm you. Saying careful flying bud. C ya John frm fla.
My didn’t explode cause I tried before but I was turned away after keeping up with some acronyms then I knew. “This requires a class a whole separate class!”. 😆. Good job explaining the difference in experiences. Thanks
"best antenna setups" begins at 9:12
Thanks again. We love you, Andy.
Thank you for this video! All your videos are amazing, thank you!!!!!
Thanks Guess I'll put mine back on. I'll be printing the Analog holder for my RapidFire
Love your vid's brother
I have always said the stock DJI ant are absolutely perfect for everyday hobby use. I know its not "cool" but ...I do like the Lumineer Axii because of the size 1 the V2.0 Occusinc RE Goggles came with linear "post" antenna. I am considering trying them ! I now take one DJI 5" kwad everyday to the field. The DJI tx. The DJI goggles. AND ITS PERFECT !! I AM getting excellent range. Beautiful video experience. LOVE the TX !!! Builds are so easy ...wow !! we are all SO SO lucky ! what an amazing leap in technology ! THANK YOU ANDY and THANK YOU DJI !! I still fly my Phantom 4 and Mavic Pro. No matter what regulations come it will not take away from the joy of flying FPV !!
Just ordered the pico setup from Race Day Quad w/ext. Thanks for the great info.
Thanks Andy and thumbs up on another one of your great videos. I learned a lot and having been a mobile phone network technician once in my past, I could connect to DJI's choice of technology, so thanks for diving into some details.
Andy your videos are the best! On point, so informative! 🙏
As usual, informative, well researched, and very interesting. Thanks Andy. I replaced my stock antennas with the TrueRC Singularity, only because it is a smaller form factor and easier to transport, as I don't like keep taking the antennas on and off.
Very informative video. Question: Is there an update after 2 years? Or are these antennas the thing to look for?
I just ordered the VAS Cyclops antenna for mine. It was on clearance for 34 bucks.
Amazing job presenting a complex topic - I just subscribed!
Good job, I almost understood everything and my headache should go away soon. I enjoy all your videos.
Just ordered cause of your vid! Stoked to see how it works!
The camera you show has 2 antennas but the links only have one.
Very good information!!!!!! Had no idea what to do about upgrading.
Exceptionally well done video! Thanks Andy! 😎🤘
Thanks for the in depth review and explanation
Most of the communications world calls TDD...TDMA time division multiplexing access, as opposed to dedicated FDMA frequency division. Google searches or you tube ones might yield better results using TDMA. Just sayin...either way, another great issue. You’re rocking it, and I enjoy all your posts
Thanks a lot for these great information
surprised of the huge info that I really first time to know all about antennas! Thanks a bunch mate!
Andy you are a true pro.
I'm in Dominican republic, right now and flying with dji all stock antennas, so far all perfect, flew couple of kilometer in mountain s and love it.
thank you Andy,, great stuff as usual. I think my next quad will have the Caddx DJI airunit. wanna give that a try.
Super interesting video Andy. Enjoyed the legal bit explanations very much!
Thanks for saving us hours of reading to ge the same information :-).
Yes in Eu you can change antennas, but in here there is thing called EIRP. Your transmitter power + Antennas Gain power is the max power you can transmit. 2.4Ghz it is 100mW about 20dBm. 5Ghz it is 25mW 5.5has DSF-channel rules but in there you can transmit 1W EIRP about 30dBm. So it is dBm+dBi. I think All transmitter here are forced to transmit 25mW. So no antenna changes yes for 2.4Ghz you can but max 6dBi antenna. And for 5.5Ghz 16dBi, but with 5.5 You have to deal with DFS connection cuts. Other frequencies even with usual 5.8 it is 25mW EIRP.
Hi . I use DJI FPV Remote Controller binned with the air unit . I suppose the embedded receiver uses the same two antennas the air unit uses to transmit to the goggles . Is it normal at about 1750 m from home position , to have a fail safe event ( FCC and LOS ) ?
You should have more subscribers your a great UA-cam
Hi Andy, do you have a video analyzing the new DJI Goggle 2, how to connect directional antennas? Other questions, Can I install on the air unit and dji goggle RHCP antennas?
Any update to this?? I’d love a comparison with the maple wireless mjorlin and the truer air2 the crystal and of course axii hd 2.
Thank you. As usual, this was a very helpful video.
The higher gain on the goggle transmitters are probably fooling the air unit into thinking the quad is closer to you than it really is so it drops the output power a bit to save on battery. The googles most likely don't do the same as you generally have plenty of power in them to last a day so they stick to whatever transmit power you set.
Bro! Science! Thanks for all your info
Nice review Andy... I use the true-rc patch ants and they work GREAT..!!! Even from behind sitting on the ground in front of my truck ...I went all around the park I fly at and the goggles where supurb at 1200mw...!!! no problems very lite latency flying at about 10ft off the ground and and oval perimeter about 600 to 700 yards...!!! And 1mile at the same height at my flying club with a few trees following the gravel road in... Elevation changes also some small buildings, trees at the park, but great video still ... I'm just amazed on how good this system is ...I'm using the full system outstanding...!!! But still like my analog ;-) But now I can use the dji goggles with all my qwads with the new adapter for analog ;-) thanks again for another great video review on the best antennas...!!!
Thanks for watching glad to hear you enjoying the hobby to the full
Andy, try being IN the Bando when you fly DJI.
Furadi thinks that the way the MIMO system works it actually benefits from the multi-pathing bounces.
multipathing just means reflections so it would help standing inside the building for sure If mimo is being used in that way although DJI indicated to me that they arnt using MIMO for that use. Turning down the power output of analogue indoors will reduce multipathing reflections. But the bando exploring I do with analogue is usually done standing outside the building and this for me is what HD fpv needs to match what analogue can do. It seems that two omnis on the transmitting antennas on the goggles helps this.
There still is the analogue delay when using analog in, no?
i dont even have a digtial system, but its andy rc so obviously im going to watch it haha
thanks Damon thanks for watching.
Can you tell me where you got the white 3D printed case that surrounds the analog RX on the side of the goggles ?
I fly long range fixed wing at 700mW and have found that a True RC X-Air connected to the top 2 antennas gives about 3 times the range of using the stock antennas. Leaving 2 stock antennas on the bottom 2 positions gives good omni reception when behind or vertically above me. I get 3 bars signal strength and 25mbps at 2.5km.
Do you mean the X2-Air, the ones on the thumbnail?
MatTheKnife 13 hi - the ones shown at 10.20 where Andy says they cost a fortune. I bought one for £47 which connects to the 2 top antenna positions and is brilliant. In fact several others in our club have done the same. Dramatic range improvement.
@@alanpaul1234 Thanks for the quick answer, did you try using only two of those, what were the results if you did, compared to the setup you just explained?
@@spanthyx Hi, I have only tried using one True RC X-Air antenna, but this has 2 patch antennas built in and 2 connectors that connect to the top 2 positions. I left the stock DJI antennas on the bottom to get good coverage above and behind me. This combination works really well - check out my test flight video and I could have gone a lot further but didn't fancy a long walk if anything went wrong LOL ua-cam.com/video/jY3FM8tmH_Y/v-deo.html
what the difference in RHCP or LHCP idk which to get, does it matter, should they be all the same polarization if i choose one style over the other??
Very new to this and looking for the best antennas for flying indoors/long range indoors. Any recommendations?
This is v1, right?
Would it make sense to put on the TX mounts a pagoda and a patch, just as I do for my analog setup on the v2? Same for rx mounts: mix a pagoda and a patch.
Most people I see using either two patch antennas or just two omni antennas on both tx and rx mounts... ?
Is the image constructed the same as with rapidfire technology, or the antenna selection is more basic in the DJI goggles?
Super interesting, will gladly be laying out for two patch antennas instead of the X-AIRs now
I thought the x air were patch antennas?
A Dji Fatshark Hd Module would be fantastic. I'll stick with analog and look forward what comes this year. I'm very excited.
Hey Andy, I don't fly bandos but simply want to extend my range ability. Have you tested both these in simple range tests and if so, which set-up do you recommend?? Thanks.
Hello AndyRC. I can't seem to locate the dji corrective len section on the dji store, not even at the search bar. Please adive and thx per request. Perhaps you can send me the link. Btw, I am in the US
Outstanding Andy. This is going to help when I actually to fly this week. Patches on the bottom it is!
Great information!
Excellent info mate! Top video 👌🏾
Cheers NJ thanks for watching
Hey Andy. I think this is the first video to do with fpv that I have watched from start to finish! Quick Question, if the antennas were all in the same price range, what would you find best to use? X Air Maybe?
I have bought a dji and protek35 backpack. I had no idea the extra antennas which are the menace lhcp did what they do, so they’ll be going straight on. There was also a red unit bolted to the side called achilles with the same lead as the one in the vid. i removed this, didnt know what it was for or how to use it.
Seems I have a bought a fair bit of kit at a great price i just use the std antennas, have jacked the output up to 700mw on my caddax unit but get pixelation at about 180m lowish height behind trees. I’ll try the menace and see of there is a difference. It has been suggested I change the antenna on the caddax unit to a taller one as it doesnt stick up very high. Are these 5.8ghz? and what should i look for
Flying in the forest behind lot of tree canopy and beyond LoS behind earth and rock, I've had positive results with two Triple Feed patches mounted top and bottom on one side. Generally worth about 1 bar in signal strength and 5Mb/s during marginal conditions. I'll try it with bottom only, but I'm skeptical that that's optimal in my NLOS conditions. The goggles tell the air unit when it has lost packets (representing frame updates) so the air unit can re-transmit them, so without any gain on the transmit side eventually the air unit won't hear those retransmit requests. Yes, maybe there's some multipathing issue for bandos, but flying behind trees and such usually just represents high attenuation (they block rather than reflect the signal). Another possibility is that with MIMO+CDD it's using the reflected signals to move data and the higher axial ratio of most aftermarket antennas (compared to stock) is attenuating the first order reflections enough to make them not useful. If that's the case then high gain on the goggles with linear antennas on the air unit might be best.
FWIW, you can see what the signal looks like without any retransmitted packets by watching someone else in Audience mode. It's not great.
As I mentioned The omni setup is for bandos which everyone is avoiding with this system, everything else you say I agree with.
Would you recommend this same setup of yours for the Walksnail Avatar HD system? Thanks!
I might pull the trigger soon😋. I want to hate them🤨 but I really do love them🥰
Everyone wants to hate them but really its the people misusing their products we should hate.
@@AndyRCchannel that is very true mate. It's the reason why all the laws are coming out. People being stupid. Keep up the brilliant work brother and happy flying to all🤴
@@AndyRCchannel DJI has brought more innovation to our hobby; in the end, that is all I care about; I don't know why some people have hatred towards DJI; I have owned their products since the phantom vision plus days; it is all great stuff, and had it not been for geofencing, I would have kept my mavic pro; the geofencing and regulations from DJI are to protect their business from people doing stupid stuff, or maybe just careless stuff that could lead to a major lawsuit. I don't care who is bringing the innovation to the table because that is what forces the other competition to step up their game.
Thank's Andy. You've saved me a lot of money. :-)
I almost had spend a fortune on the TrueRC X-Airs.
My true rc x airs seem to be the best in nearly every situation for me, go behind me quite often and I pick up easily a half mile.
@@trowland9575 Yes that's
unquestioned true. But the menace perform very good too. For much less money.
Can you do a video on the dji fpv transmitter and antennas please
This is specific to the Video transmission, correct? Hence why to leave those two antenna on the air unit? I plan to use Crossfire for my DJI setup with the micro transmitter and the crossfire nano rx on board. Great video!
Funny I thought I was going mad when I was getting better data and picture flying through our woods on stock antennas as opposed to the menace patch antennas, I had them on the top, now I'll put them on the bottom and see how it goes, but at least I know I wasn't nuts.
Also I cannot fault DJI after sales service either, my Air unit stopped displaying the osd one day and then died completely on the suggested firmware update, emails back and forth (even on Xmas day!!!!) resulted in the unit being collected by their repair centre in the Netherlands and then replaced by them, all at no cost to me (even when I forgot to put a cable in the box, THEY collected it from me - must have cost them 40x the cost of the sable to get it collected lol) and this was outside of their DOA warranty period, so all they were obliged to do was repair my existing unit, but they still went ahead and replaced it anyway.
I'm curious to know the results. How did they perform on the bottom... in comparison?
You know? Come to think of it, I don't have Menace patches, but I do have two single TrueRC X-Air patches that are LHCP that I would try on the bottom position. I'll give that a test myself back to back a few times.
PinchTune I haven't tried yet as I need the 45 degree adaptors, plus the fun police are doing their best to stop me flying the drone at the club. CAA and media don't need to do anything to cause divide in clubs, still enough of that being done by club members themselves 🙄
Do they make goggles for a DJI air 2s
Very knowledgeable and helpful information,thanks Andy
Me personally always like to see your ideas about any products which comes out about racing or freestyle multi rotor quadcopter drones 🥴 anyways
Waiting to see more from you and stay safe,cheers
thank you very much for this video...i learned a lot. with all these new products it is kind hard to decide what to get. my first concern is if i buy dji fpv air combo with goggles and transmitter will i be able to use 700mw in europe?(i guess at the moment it is an easy software mod but what if dji decides lock that option?do we stuck with only 25?)the other concern is....should someone buy dji transmitter if starting from scratch or get a taranis x9d se 2019 or even a tango2 and use air unit only as vtx....my head is about to explode indeed....keep up the great work
Thanks for all you do😎👍🏻
Great explanation. Thanks.
Thanks Andy!
brilliant review, and brilliant product, i can't wait to get these goggles, i wish they were a bit cheaper
Madmacs FPV totally new to all this, but by the time you buy the Fatsharks, receiver, antennas etc, DJI comes out cheaper! Kind of crazy. And don’t get me wrong, I always root for cheaper ;)
@@dmalovic cheaper and better
Very interesting stuff Andy. I have no problem with the stock antennas, but I did notice that the stock air unit antennas are not very durable. I mean, I'm actually very easy on my gear. But I literally clipped a twig flying under a tree and one of the caps came off. Do you know if the cap itself works in the polarization (like on some VAS antennas)? Or is the cap just plain plastic and all the of the antenna elements are on the inner portion only? Most of my other antennas will take a beating before losing a cap.
Good info again Andy, nice one.
Why trueRC suggest to connect the patch antenna to two top SMA horizontally when not used in pair (2x2) ?
HI Andy, fellow UK flyer/complete noobie here. What a steep learning curve this all is, my head is about to explode. Anyway im not sure if you mentioned it but when purchasing the extender kits there are three options.
SMA to SMA
SMA to RPSMA
RPSMA to RPSMA
what would be the correct one to get with the menace PICO?
Incredible video!
for the bottom pair of antennas, does it matter whether the pair is LHCP or RHCP ?
The best explanation! , here is your like Sr.
Does it work with kiss fc yet?
Hi Andy, great video. Could I ask what antennas would you recommend for a flying wing setup with dji digital system?
I'm waiting to get mine, to put it on an Opterra 2m flying wing. The type of "flying thing" doesn't have much bearing on the RF Tx and Rx performance. Go for what Andy recommends. The best way to improve performance of this system, or any RF system, would be to get the antenna up and away from the goggles/head themselves. I would love to be able to separate the goggle screen gubbins from the RF gubbins and place the RF gubbins on a 5 metre pole. And range/performance is less about Tx power, more about Rx sensitivity and Rx ability to discriminate the signal it wants from other signals and the noise floor.
You've metioned that googles antennas are left hand polarised - do I have to put antennas with the same polarisation onair unit or I can use right hand polarised?
You need to use left-hand polarised
I agree with the silly regulations. Andy I'm giving everyone an update on the 182 thousand fine the FAA gave me.. I think you all will be very surprised of the outcome if that's what you want to call it? Bottom line is there silly like you said and seems as if you only have say one thing do VOID all regulations.. (which I actually agree with... We need rules... Just not stupid ones....) THANKS for your hard work mate! Flying rc is not a crime!

Alot of good information here Andy! Your discovery at 7:08 that the google's does not transmit when there is no air unit powered on means that it's possible to use analog input without dji antennas connected or may it suddenly start transmitting if discovered another 5.8 ghz signal?
The only thing i like to know is what are these upper antenna sending?
lots of thing, if you change the channel on the goggles then it sends it to the air unit. It sends the record commands. Pid settings, camera changes. But way more which I will cover in another video

@@jorgeromero4680 no, you did
Thanks Andy! One question. Since only the top antennas of the DJI goggles are transmitting microwaves, would it be safe to have patch antennas on the bottom only, such as the Iflight crystal patch, and use stock antennas on the top?
Love my DJi goggles but seems everytime I use them for more than 2 packs I get a massive headache. I'm contemplating even keeping them now. I've already had cancer 3 times since 2010 so don't need brain cancer next. Lol. Still great system but unfortunately think I may not be able to use them.
DJI has since applied to fCC for a V2 version which runs on different frequencies 2.4ghz+ and 5.7-5.8ghz+ which leads me to believe they may have been forced into changing this platform for obvious reasons
Question.... if the top antennas send+receive and the bottom ones only receive , why don’t we place two different type of antenna as we do on current analog modules? I would try a patch and a stubby on the top antennas and same for the bottoms. In this way you are also using the capability of a patch antenna in the transmitting ones.
Because they don't work in diversiry like analogue they are all collecting data so if either of the top two or bottom two have a different antenna then only the strongest gain will collect the most data
So I don’t destroy the goggle, when activate the air unit and don’t have attached antennas at goggle ?
