This video briefly shows how to setup and use the NanoVNA to sweep an antenna system (antenna, transmission line, transmatch, etc.) to measure its VSWR, Reflection Coefficient, etc., and then shows how you can use it to monitor the tuning behavior as you make adjustments. The basic steps include:
- Setting the traces that you want to display (SWR, Smith, S11)
- Setting the frequency range
- Running a Calibration
- Making the sweep
- Using Markers
Please see my previous videos on the VNA, Smith Chart, Transmission Lines, Terminations, etc. for more background.

From what I see in the comments and having bought one myself. The folks who sell this VNA should as least pay you as an instructor if not for the boost in their sales. Thanks for another set of helpful insights in both using this device and our equipment.

@David Hogg How do I get on the "IO" forums? And how can I get one of the good ones (Noelec? Hugen? Deepelec?)

Not everything has to be about money.

@wb7ptr 2 года назад

The only complaint I have about it is the the manufacturer hasn't provided more detailed instructions for it's use. A lot of the purchasers are NOT engineers. A lot of ham radio operators are buying these. Some are engineers and some are not. I think a professional engineer would get the hang of it pretty quickly. The rest of us need a bit more help.

Bill-N6EF-Thanks for a another great NanoVNA video. I'm learning a lot about the NanoVNA from your videos. I never really understood the value of the Smith chart until I saw how you used it in this demonstration. I usually turn it off and only look at the SWR trace. I will be experimenting with my tuner using the VNA to get a better match other than SWR.

@w2aew 4 года назад

I went with the NanoVNA-H4. The NanoVNA-F has a similar sized screen but in a metal case (nice). There is a new v2 that is just coming out now that goes to 3GHz. Firmware is a little behind the original (doesn't interpolate between calibration points - thus you have to calibrate with every frequency setting change - good practice to get into, although this forces you to do it).

@EngineeringVignettes 4 года назад

I try not to mention other channels normally but TomTekTest (TTT) just put out a comparison video on the NanoVNA options about 30 min. Prior to this comment. I have not watched it yet tho.

@adriancressy8363 3 года назад

THANK YOU. I bought one of the NanoVNA from Amazon and got the "upgraded" unit. The accuracy of these analyzers will help the operator to get the most out of their system to the distant station. Many analyzers are not very accurate and optimization of the antenna system is not even close.

@AlastairMcGowan-kn4vs Месяц назад

That was easy. Helped me get off to a good start. Second time I made a mistake and did not remove the test load before clicking Done, but now I remember the process it should be simple

@JustLearning 3 года назад

I have a NanoVna and find it really useful. I will use one function at a time. I mostly want to see what my Handy Talkie antennas are tuned to from the factory. But I may start to make my own antennas and will need to make them resonant at a particular frequency and the NanaVNA will come in handy then. Thanks for the video.

@@sirhaugen1025 Hi, I was able to read swr after this video but I think my nanovna has some problems. Sometimes it doesn't show any readings for a minute or two and after it is working the swr reading are way off compared to my swr meters, more then one. But it did read correctly on my 2 meter J-pole. I might try to install the firmware to only use it for swr readings and see what happens . But I am not happy with it the way it is. Thanks, Carl

@danny_mixmandan_james 2 года назад

Just brought one of these and to say mind boggled is an understatement! Brought it to check the SWR and tune my loading coils on my Diamond CP6S - at least I know sort of where to start as never used one of these before - always adjusted, gone back to the radio and checked the SWR - just trying to work out how to connect the PL259 to it! It’s one of those small adaptors that came with it... I hope!

@w2aew 2 года назад

It likely did not come with an adaptor for PL259 - you'll have to pick one up yourself. The bits it came with are likely the Open/Short/Load and Thru devices that you use in the calibration process.
