The NanoVNA provides alot of value in a tiny size. It has features that go beyond what we need most of the time with amateur radio, so there is a bit more complexity to the unit. With that said, if you have a bit of patience you can learn how to use this for your antenna building.

NOTE: the $50 price is when purchasing through Aliababa. It's more expensive if you purchase it through Amazon.

@TheCablebill 4 года назад

I paid about $35 on Aliexpress.

@Blue-Collar-Radio 4 года назад

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.

@brianjensen5200 2 года назад

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.

@gr33nshoes 2 года назад

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 2 года назад

Knowing what you know now, would you still purchase this?

@gr33nshoes 2 года назад

@@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.

@daviddawkins1 3 года назад

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!

@brentjohnson6654 4 года назад

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...

@terryburge6763 4 года назад

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

@bill-2018 2 года назад

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.

@ElPasoTubeAmps 3 года назад

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...

@JxH Год назад

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.

@MegawattKS 3 года назад

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.

@denp54z Год назад

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.

@Blue-Collar-Radio 4 года назад

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! 👍

@John_Henry83 Год назад

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 !!!!

@davidj.wilcox6053 4 года назад

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 plan on feeding it with rg8x and a 1:1 coax balun air-wound around a PVC form. Do I scan this antenna for trap adjustments with or without the balun in line. My mind says WITH but as I said, I'm kinda new at this. Any info would be greatly appreciated! Best regards, Cliff. Florida/USA

@donepearce 5 месяцев назад

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.

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

@HamRadioCrashCourse Год назад

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!
