[Upgraded] AURSINC NanoVNA-H Vector Network Analyzer 10KHz -1.5GHz Latest HW V3.6 HF VHF UHF Antenna Analyzer, Measuring S Parameters, SWR, Phase, Delay, Smith Chart

This is a great way to see where an antenna is resonant and what its swr is. Look on youtube for tutorials on calibrating and usage. It is far more capable than swr but that is what I bought it for. I disregarded most of the 1 and 2 star reviews as 99% of them were because of lack of a manual and complexity of calibration. A printed manual would be 2 inches thick because of the capabilities of this little jewel. My only problem was with the microsd card not saving. Not a deal breaker for me. If you have the bucks you can buy a Ukrainian built antenna analyzer. The nanovna works for me.

Absolute best value in equipment for tuning HAM anenna SWR. I have nothing else to compare to, but the radio performance bears out the apparent goodness of the reported readings. I managed to get the software stuck at one point messing with UI touch calibration. But a factory reset cleared it up. Huge amount of HOWTO resources on Youtube. Fully equipped with stylus, adapters, calibration accessories, a cheat sheet for the menus.

Really amazing little thing for $50. There's a steep learning curve since the UI is kind of cludgy, but plenty of YouTube videos to explain it. This particular model only scans 101 points. The upgraded model, I think the H4, does 401 points. If you want to scan wider ranges of frequencies, you'll be much happier with that one. This is fine for sweeps of reasonably narrow bands if you are checking antenna performance. The resolution on the screen is dismal if reading the Smith chart is important. Especially if you have older eyes. Be sure to invest in some SMA adapters. This has SMA threads on it. You'll probably want to grab some SMA - UHF, SMA gender changers, SMA to Type N, SMA to BNC type things.

This tiny device packs a suite of powerful network tools. Its simplicity helps me incredibly in the ham radio space. I get quick and precise SWR readings, and I can see the other frequencies where the antennas resonate well. Besides, it is very portable.

Very nice and easy to use tool. I am new to antenna design and this tool has helped me understand and learn more about the craft. Great price.

So good I bought two!

Super product! This VNA lets you cut, tune, and/or match antennas to resonance. There are a bunch of youtube videos showing how to use it.

I was skeptical but this is a great analyzer for HAM antenna measurements. Impressive for its size and a good value.
