[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.

I have to admit that I am still learning all of the capabilities of this unit. It has helped me to make several ham radio antennas without the fear of damaging my radios. From what I have seen so far this works just as good as the much more expensive ones.

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.

Great little vna. My next purchase is going to be the NanoSA. The storage box is nice quality and been very useful for keeping everything I need in one place.

So far it’s working great! In two weeks used it to tune in a home brew 10 meter moxon (ok not hard since it’s so wide banded) a 2 meter dipole and a test an existing home brew 70 cm/gmrs 9 element Yagi wow thanks! No photo from the 2 meter dipole.

Wonderful device that helped me tune several antenna’s from different radio bands. Worked perfectly and was easy to figure out. Very pleased with my purchase, Thank you!

Very nice item, at a reasonable price 👌

Good for any Ham guys.
