NanoVNA - SWR Reading Made Easy
HTML-код
- Опубликовано: 8 май 2024
- A nanoVNA is a portable and affordable vector network analyzer used for measuring and analyzing the performance of radio frequency (RF) circuits and antennas. The process of making an SWR reading looks daunting but it isn't as hard as it looks!

If every instructional RUclips video was as excellent as this one is, I'd be a lot smarter. Thanks!
Not sure if this matters for this particular device, but I was taught that you should always do a calibration in the config you are testing with, especially if there are any adapters, extensions, couplers and the like involved. Basically to hook up everything except the DUT, then perform the open, short and load calibration.
For sure that is the correct method, but just how much difference will there be in the real world between calibration at device vs calibration at DUT?
I’ve been using the NanoVNA for swr metering for a while now. I just don’t use it often enough to remember the simple manipulation every time even though it’s not that complicated… Your short video makes it easy to undestand and takes the complexity away from it. Good job !
It’s a great tool and I wish I could do more in the shack or in the car with it. Please post other tutorial that are amateur radio oriented for the NanoVNA.
Just got mine today, I'm glad I ran into your video, very informative. Thanks
Best tutorial I’ve seen on this device!
What a simple, but clear explanation.
I wish i had seen this before my struggles
This is the best how to video out there. Thank you
Well i made à 2m antenna yesterday for the car. I used a standard swr and power meter.. Calibrated with a 50 ohm load . I adjusted for minimum swr. It works well.. I agree the nano vna provides more info. I do have one, but cannot get out of my old habits. Thanks for your time and info.
Best I've seen. Why? I'm a new ham setting up my station and I bought the nanoVNA H4 as the most economical SWR test device on the market for helping set up an antenna. I discovered, as many have, that it comes with no instructions whatsoever. I looked a t a few other videos before I found this one. Had this been first, I would have been happy. That said, I do plan to explore at least a few of the many capabilities the nanoVHA has.
thanks for the plain and simple explanation on how its done, I had my vna a long time and I still struggle to use it, now I will refer to your video for reference.
Thank you for a very nice and easy go thru of measuring an antenna. I got my Nano VNA in the mail today and didn't have a clue on how to begin using it! Now i know the basics. 73 de SM6VIT
I appreciate it you really helped me all the other videos I looked at I couldn't understand but I understood yours and I actually got the swrs checked on my antenna and it was 1.15 I just wanted to thank you
Excellent video. Very concise and only the information we needed.
This video is the best I seen on this unit
Many many thanks for this important video ❤
When, inevitably, someone tells you "Never spin on the whole connector", then hand them the one-piece 'Short" and ask them to show you the correct method. Hopefully at that point they'll shut up.
Thank you for the video - been wondering about those NanoVNA for a while. I think I might order me one.
Thank you for the useful video.
Best thing I bought last year. A great bit of kit for the price. Good video.
No guessing is it too long or too short as I did with just an SWR meter.
My 10m dipole 1.15:1 with the SWR meter just lifting off the end stop. Calibrated to the last reading of 1.5 so anything below is great. H/b resistive type SWR meter. Need to do the other aerials since I moved them.

thank you for a simple guide to what must be the most useful function of the Nano VNA. Richard G8ITB.
Excellent video on the NanoVNA. I was looking at buying something to measure my antenna SWR and considering the NanoVNA. Your tutorial is great for starting. Thank you so very much for sharing. Could you do one for the HF frequencies. I have seen other videos but, not as clear as yours. Thank you.
Thank you very much! I just purchased a Nano VNA and was looking for a basic instruction on how to use it.
Glad it was helpful!
Could you please let me know what the 250 in yellow before the swr reading relates to, as I have not been able to find an answer. Thanks for the help and time, with with the video! @@HamRadioHobbyist
Thanks for this video. I have never used a VNA and I am looking to test out some Meshtastic antennas on 915mhz.
Thank you for the video, nice job. When you save a calibration, does it keep it after shutting the unit off or just for the session?
Great video, but do you not need to do the THRU calibration, connecting a cable between the 2 ports?
Excellent video - great explanation! If you don't mind, could you share your NanoVNS information (make, model, purchase location)? Thanks a bunch!
"S eleven" is better pronounced 'S one one', as the "11" means port 1 and port 1 for both out and in.
hi did test on my scanner ... using vna .. swr 1.4 ,,, not bad ...... logmag - down 90 what is that
Don't need to enter the ".00"; just 144M is enough.
That should be titled made more difficult.
All of the recalibration crap sucks.I will just keep my MFJ 269 and be happy.
Why?
About maybe 15 minutes to calibrate 5 memories, then just recall.
I have 4 to 8 MHz for 60m, 3 to 10 MHz, 10 to 20, 20 to 30 MHz and 20 to 265 MHz.
Nothing difficult.

@@bill-2018 I can do every band and Never recalibrate anything with the MFJ.
That’s fine if you can afford to buy one of those. They are about 8 times more expensive than the Nano VNA.
@@bak2bassix I already have the MFJ 269 so I don’t need to buy anything.I covers all of the bands that I use and it’s very simple to operate and it works great.
@@1OFGODSOWN Yes, they seem good, I did consider one at the time but opted for this..
