The linked nano vna, in your description is the same one I purchased. Mine did in fact come with the shielding, case, and calibration kit. I felt the extra cost was worth not waiting for delivery. Great video! 73!
I ordered the "updated" model for use with Android. But haven't tried it out with the app yet. Of course for all I know they might all be compatible with the android app. I clicked and ordered. And it works at least as a stand alone. $62 on Amazon, prime next day delivery. As low as $35+ shipping from AliExpress w/2-3 week delivery estimation. I bought from Amazon.
It might be worth adding, for those who haven't found out yet, that the little NanoVNA becomes MUCH MUCH better to use, and much more powerful when used connected to a PC running the program for it. You can do more stuff that way, and you get it bigger size so easier to see and work with.
After watching your video and about 20 others I actually bought one of these units and even after watching all these videos I was still frustrated and confused. I watched this video again. Watching something in theory and actually using it, and having the device in front of you, is very different. I'm finally able to analyze the antennas which I build over the years. Mostly accurate results, some surprising results (especially my HF antennas).
@@johnd8224 Yes. It's great for the price. I don't use it that often, but for more things that I intended to (which was to measure my DIY antennas). However, I sometimes have to fresh up my knowledge by looking at a quick video.
Thank you for this. I purchased one last month. I have already thrown away 2 Antennas I purchased from China on ebay, as they were so off frequency ( or were just broken) Your video has definitely prevented me from damaging my expensive radio equipment. It also goes to show how many of these Chinese companies ' Lie' about frequency range of antennas. Much appreciated!
Thanks for the explanation! I finally got one of these, so I'm back to review how to use this. Honestly, the paperwork that comes with these is out of my league!
Thank you so much, that's perfect. I had bought one for Amateur radio and was overwhelmed by the menu structure map that came with it, not sure where to begin. This video explains exactly how to do what I need it for :)
Ordered an updated version from R&L a couple of weeks ago. This came mounted in a metal case and included a carry case. So they have been improving these over the past year.
Many thanks for this VERY educational video. Easy to understand, and I appreciate you showing the calibration too. I was considering one at £320 around $400 but I think I will get this one instead now. I am not wanting accuracy to 0.0001MHz so it will suit me just fine. Thanks again. Keep up the good work.
I got one of those cheap analyzers not too long ago and used it to check commercial 460, 700, and 800 MHz antennas as well as an FM broadcast antenna and it worked good enough to be in the ball park.
A big THANK YOU for this video, as it sure did help me figure out the user interface. This is one mighty useful device, as is your video. I used H-P VNA's decades ago and never imagined I could hold one in the palm of my hand. At any rate, I am off looking at all my antennas at the moment. Thanks again.
This video is awesome I got one last year and the only info that came with it was the command prompt tree, nothing about general use. Which kind of added to the stress with getting my license.
I bought one for myself (early Christmas pressie £30) prior to your video ..fantastic bit of kit. Thanks for your video on these too - 73 and Seasons Greetings to you and All the viewers de 2E0XBT
These instruments are great . I use mine for SWR tuning but it does so much more I m planning to learn on testing 50ohm cables. But there are plenty of great tutorial videos to learn from on line like by this UA-camr . Thanks !
Hi. Brand new to your channel. I just got mine in the mail. I paid 84 dollars for mine, but it does go from 15 k up to I think its 12 or 13 hundred MHZ. So far, I'm very impressed. I did a search and your channel popped up. Great intro to this device. Thank you for making this vid. 73, de KD7SJT
Tips: 1) For trimming HF dipoles, the Open/Short/Load calibration process (that is related to amplitude and phase) isn't all that essential if your primary concern is simply finding the FREQUENCY of the dip. Skipping that process can save a lot of time. If you're worried, then the final confirmation measurement can be oh-so carefully calibrated if you wish. 2) One can purchase SMA-male to SMA-female adapters (which do "nothing" adapter-wise) to act as 'Connector Savers'. This entire concept is less critical on a $50 gadget than a $50,000 instrument, but these adapters are very very cheap. 3) Order a spare set of Open/Short/Load sooner than later. You'll need them eventually. 4) When (not if, LOL) you trim your dipole an inch too short, then add a little tab of aluminum foil tape around a square inch at each end of your too short dipole. These foil tabs act as 'top hats' and will drop the resonance enough to allow you to then trim the foil to hit the target frequency. 5) When watching someone that doesn't know about NanoVNAs fiddling with their $350 MJF Antenna Analyzer, try not to smirk. It's rude.
Excellent. My Elmer just recommended I get this for building and verifying my antennas over the standard SWR meter. Looks very capable. Just need to protect it more. I would think a plastic case housing it with a SMA to UHF connector would be wise. Of course the calibration would have to be done with the SMA connectors. I can’t believe the price though. Network analyzers we used at work back in the day would have been $1000s or $10,000s. Now to get educated...
Ok. I'm sold. I'll get one of these to figure out what the hell I've built ;-) Oughtta be pretty handy once it warms up enough for me to start hanging wires again. Thanks for the video.
Nice video! I just got one from Amazon and love it. Paid quite a bit more, but that's because I wanted the 4.3" screen. And it came in a very rugged metal case. It's the "NanoVNA-F" and it came pre-calibrated from 50 kHz to 1 GHz (vector S11 is cal'ed to the SMA connector reference plane, but its fine without re-cal for SWR or S11 log-magnitude plots in any sub-frequency range). The SOLT cal can still be done if you like, and the frequency range can be expanded to 10 kHz to 1.5 GHz if you do. NanoVNA makers continue to add improvements to hardware and firmware designs on all the various models - but this one is amazing. Kudos to BH5HNU and deepelec who is the developer/manufacturer of this version V2.3 hardware with S/N 30XX firmware.
Have you tried it using bit on your computers with their latest v soft war programs yet ? I bought the larger one too because I don't see as well as I use to. I have a smaller one someone gave me too but I never really use it. I guess I will give it to someone who wants to try one out.
I appreciated this video very much. I recently bought one of these VNA's off ebay but have been very hesitant to try it out. Being used to MFJ-259b's and my Rig Experts AA-170 (like yours which I have a lot of confidence in) I'm just not sure how to use the VNA. Yet I see these You-Tube video's with other hams using VNA's and raving about them. Also talking about figures I'm never heard of. I subscripted to your channel hoping to learn more about using these. Right now I am faced with the problem of running coax and control cables to my tower of 118' with my 3 ele steppir on it. I got the bad idea of seeing if I could get the coax and control wires off the ground and of course developed and open or short. So basic of basic, I am once again trying to figure out the best way to run about 200' of coax and control cables to just the base of my tower. Running wires has always been a challenge for me. I hate it. Terry
Hi, Josh. Good review, thx. Just ordered the "upgraded" version, 10KHz to 1.5GHz. Total $56 with an online coupon. Be here in 2 days on Prime. I may be back with a review soon. 73
Nice demonstration. I have one but I never thought of using the end of a hard plastic pen instead of that guitar pick that comes with it and dragging the cursor around. Mine is fully encased in plastic which surely makes it a little safer from damage. I think mine was up to about $75 off Ebay. Stay safe...
I bought one a couple of weeks ago. A very handy bit of test gear. I've checked my h/b dipoles: I got the SWR down but they are slightly too long to be spot on frequency, I looked at my h/b magnetic loop as I tuned through frequencies and checked the performance of a h/b filter for 9MHz. The only thing I would criticise is the tiny screen size, I have to use a magnifying glass to read things. G4GHB.
Thanks for the informative review! I have been looking for something along these lines for tuning my UAS antennae. You might drop a few keywords in your description for tools and info like this as I'm sure I can't be the only one looking for info on this stuff and a little more unity between the ham and fpv crowd would be great for both I think.
A friend gave me one of these as a present a few months ago but it seemed kinda complex. Finally I know how to use it, thanks to your video. Thanks! de ND1L
very nice. The tinySA ULTRA 100k-5.3GHz was used in setting up a backyard 21cm 1420 MHz radio telescope dish. So I am watching how to videos on making a R-scope. 😎 Thanks.
I also have the high end Sark 110 but need the manual to use it each time. My Nano works well for general ham radio antenna testing and filter analysis and is simple enough to use without going back to the manual. Every shack should have one of these.
I would love to see a side by side comparison of impedance and swr between the nanovna and your rig expert to see how closely they agree. I'll beg haha. W0AAV.
Josh could you in the future use this in a field setting on “How to test a mobile vehicle antenna set up on a rig? I’m looking at buying one to test my truck set up, specifically SWA, I just bought a Yaesu FTM-400XDR/DE. Also just bought a XIEGU G-90 🙂. Definitely going down the rabbit hole.
The NanoVNA is an extremely precise instrument. If you perform the calibration sequence properly it compares very favourably to a Keysight VNA costing tens of thousands. It is almost certainly more useful and more accurate than anything developed specifically for amateur radio. Now - calibration. When it asks for the open, put the open cal piece on, don't just leave the cable unterminated. You get timing errors this way. Finally, leave the format as return loss. This is a much more useful set of data than SWR.
FYI, the cheaper Amazon sources sometimes ship with silk screen defects and take longer to arrive. It was worth the 1 month wait to save 25.00 to me. The printing defects were non issues for me.
Thank you for showing this in action. It is a great option for those with a small radio budget. I will be picking one up to go with my bitx Muahahahahaha
I have a Ranger 400 watts in a kenworth. I love too try it out on my truck too see if different locations of the antenna too find best locations also test different antennas.
Just got the latest version with the larger screen. Very impressed so far, but now I'm going to have to go back and study Smith charts. Is it necessary to calibrate for every use AND every change of frequency spread?
Great representation of the Nano VNA. The one on your link is the exact one I bought. I did a product review on Amazon on 11/9. The one I received has the shielding. Does everything I need it to do, at a price I don't mind paying. Just get a 3D printed case and screen protector and you're good to go! 👍
Hi Josh most excellent tutorial on this vna been looking at other videos on here who seem to think they know best I got this straight away 👍 and it got mine working straight away thanks By the way when you calibrate why don't you use the open like the others do ? I've noticed most of them do any reason ? Many thanks
If you’re calibrating to an open lead then it’s already open. I didn’t find much different with or without in most cases. You can try it yourself and report back.
With mine. I have to calibrate every band/ for the bandwidth that I will be testing. In other words, if I test for 70cm and calibrate then try and test for 2 meters the reading will be wrong on my Nap VNA. I would have to recalibrate for 2 meters before testing. It doesn't bother me to do so. Just something I noticed. Thanks for the video!
This meter will be the go to unit. Can you expand the training on this unit to include vector, antenna types. etc. testing cable lengths to frequency etc.
Very interesting, I have a sark 100, and while it was reasonably accurate, it isn't now. I was considering 1 of these, and after seeing your video, will invest in 1 later next year.
@@Flip2Flower1 , I have found the Sark sensitive to voltage, if the power supply is not 12 volts , it gets upset. I discussing internal AAA batteries, but it chews through them,. Also I calibrate it regularly, and it is with in .3 to 4 , on Vswr. Which is close enough for most radios.
I have seen at least a half dozen videos explaining how to use the NanoVNA. They all have ONE THING IN COMMON. Whenever the creator connects the lead to and actual antenna he moves the lead out of the frame of the camera or does not show the connection at all. Its like the NanoVNA just magically connected to a standard coax plug without the need for and adapter or anything. It is similar to when a content creator reviews a rig in great detail. Going over every button and screen But the right just MAGICALLY TURNS ON !!! i.e. they never mention that you have to connect the rig to a power supply !!!!
I have one, and while it's a great device at a fantastic price, I find it just a bit... small. There is already a new version with a larger screen (and larger battery) and there is talk of improving the actual circuit as well.
Cool little gadget and very informative video, but you can tell the difference in quality between the Nano and the RigExpert just by looking at them on the screen here, and the Ukrainian-made RigExpert takes the cake. I purchased a RigExpert AA-230-ZOOM a couple of months ago and love it. Just wish I could’ve found an equally good deal on the one that goes into the UHF range. As a matter of principle, I stay away from Chinese products.
Just got mine. And 50 years ago. any thing near it was the size of a small fridge and had a key board, and a printer . So 50 years separate me....my school years. So it's a real eye opener. Ps school was the south eastern signal school. Fort Gordon Ga. I feal have gone from the engneer of a steam ship to trying to run a atomic sub. I get the theory. ...just the tools change. thanks om 73 kv4li sgt williams out
As long as it has a shield is it "official"? I see some have a plastic body while some have the layered metal frame. I have the layered metal frame and it's an absolute joy of a piece of test equipment. 🙌🙌
NOTE: the $50 price is when purchasing through Aliababa. It's more expensive if you purchase it through Amazon.
I paid about $35 on Aliexpress.
The linked nano vna, in your description is the same one I purchased. Mine did in fact come with the shielding, case, and calibration kit. I felt the extra cost was worth not waiting for delivery. Great video! 73!
I received my first oscilloscope and signal analizer with tracker and a 60 mhz wave form signal generator. It's on my channel. Just click the E icon.
Payed 53€ for german Ebay dealer...send from Germany so no customs stress

Skipping that process can save a lot of time. If you're worried, then the final confirmation measurement can be oh-so carefully calibrated if you wish.

3) Order a spare set of Open/Short/Load sooner than later. You'll need them eventually.
4) When (not if, LOL) you trim your dipole an inch too short, then add a little tab of aluminum foil tape around a square inch at each end of your too short dipole. These foil tabs act as 'top hats' and will drop the resonance enough to allow you to then trim the foil to hit the target frequency.
5) When watching someone that doesn't know about NanoVNAs fiddling with their $350 MJF Antenna Analyzer, try not to smirk. It's rude.

This thing is insane even for diagnostics of coaxial connections in my scientific equipment (they sometimes broke, usually at the connectors).

Wish we had these when we were in our antennas course at the university. Of course, at the time, a four function calculator was considered advanced.
Thank you for the video. I was considering buying a RigExpert, but bought a NanoVNA instead.

Thanks for the vidio. The MFJ one is $300. That looks like a great and more portable alternative.
I was actually looking at this today...
Very, very interesting little unit. My only concern would be the accuracy of the analyzer. Thank you for letting us know about these.
It is accurate for SWR, but it’s finicky as a spectrum analyzer.
Just got the latest version with the larger screen. Very impressed so far, but now I'm going to have to go back and study Smith charts. Is it necessary to calibrate for every use AND every change of frequency spread?

Hi Josh most excellent tutorial on this vna been looking at other videos on here who seem to think they know best I got this straight away 👍 and it got mine working straight away thanks
By the way when you calibrate why don't you use the open like the others do ? I've noticed most of them do any reason ?
Many thanks
If you’re calibrating to an open lead then it’s already open. I didn’t find much different with or without in most cases. You can try it yourself and report back.
Dummy load? Took my boy a while to figure it out. Looks good will consider device. Thanks and God bless. Kv4li 73
With mine. I have to calibrate every band/ for the bandwidth that I will be testing. In other words, if I test for 70cm and calibrate then try and test for 2 meters the reading will be wrong on my Nap VNA. I would have to recalibrate for 2 meters before testing. It doesn't bother me to do so. Just something I noticed. Thanks for the video!
This meter will be the go to unit. Can you expand the training on this unit to include vector, antenna types. etc. testing cable lengths to frequency etc.
Very cool man I wanna get rid if my MFJ now and get a NanoVNA. Looks way cooler and stuffs.
They’re kind of different though.
Very interesting, I have a sark 100, and while it was reasonably accurate, it isn't now.
I was considering 1 of these, and after seeing your video, will invest in 1 later next year.
Jeffrey Lord glad you posted this, because I was on the fence on buying a sark
@@Flip2Flower1 , I have found the Sark sensitive to voltage, if the power supply is not 12 volts , it gets upset.
I discussing internal AAA batteries, but it chews through them,.
Also I calibrate it regularly, and it is with in .3 to 4 , on Vswr.
Which is close enough for most radios.
I got one of these used on ebay for $30. It works just fine, but the scroll knob on top was broken off. Luckily there’s a touch screen.
Can it measure single port coax loss like the Anritsu? Or distance to fault ??
Any videos on those features?
Thanks.
I have seen at least a half dozen videos explaining how to use the NanoVNA. They all have ONE THING IN COMMON. Whenever the creator connects the lead to and actual antenna he moves the lead out of the frame of the camera or does not show the connection at all. Its like the NanoVNA just magically connected to a standard coax plug without the need for and adapter or anything.
It is similar to when a content creator reviews a rig in great detail. Going over every button and screen But the right just MAGICALLY TURNS ON !!! i.e. they never mention that you have to connect the rig to a power supply !!!!
I have one, and while it's a great device at a fantastic price, I find it just a bit... small.
There is already a new version with a larger screen (and larger battery) and there is talk of improving the actual circuit as well.
Cool little gadget and very informative video, but you can tell the difference in quality between the Nano and the RigExpert just by looking at them on the screen here, and the Ukrainian-made RigExpert takes the cake. I purchased a RigExpert AA-230-ZOOM a couple of months ago and love it. Just wish I could’ve found an equally good deal on the one that goes into the UHF range.
As a matter of principle, I stay away from Chinese products.
thanks
Verry intresting!
Just got mine. And 50 years ago. any thing near it was the size of a small fridge and had a key board, and a printer . So 50 years separate me....my school years. So it's a real eye opener. Ps school was the south eastern signal school. Fort Gordon Ga. I feal have gone from the engneer of a steam ship to trying to run a atomic sub. I get the theory. ...just the tools change. thanks om 73 kv4li sgt williams out
As long as it has a shield is it "official"? I see some have a plastic body while some have the layered metal frame. I have the layered metal frame and it's an absolute joy of a piece of test equipment. 🙌🙌
