Tech Minds: Testing Antennas with the VNA N1201SA / PS100

Over on his channel Tech Minds has uploaded a new video where he tests the N1201SA / PS100 vector impedance analyzer. This is a US$160 antenna analyzer from China that allows you to measure the VSWR of your antennas. In the video Tech Minds explains a bit about VSWR, and goes on to show the unit in action on several of his antennas.

Compared to the NanoVNA V2 these units seems less useful with a smaller frequency range, and are also more expensive. The unit is also only 1-port, meaning that it can only do S11 measurements and cannot analyze devices like filters. But on the other hand it does come in a metal case with a battery and has a fairly easy to understand and use interface.
