I just received a nanovna, which costs a whole $50 or so, and some hardware needed to make it work. To think a $50 device is comparable, and in some ways even more powerful than a $600 AIM4170 from 5 or 6 years ago...
Just a quick few pics from me playing with two different antennas... Unfortunately its dark, cold, and we have bad weather coming in so I am doing what I can inside... Two different antennas magnet mounted to a circular pizza sheet, and a third antenna currently about 4 meters away from said antennes hooked to the second port (s21) to measure gain.
Antenna 1 is a 2/6 meter dual band antenna. 2 meters, then 6 meters.

The second antenna is a 2 meter/70 cm antenna. First is 2 meters, the second is 70 cm.

While I chose these options, there are many more options available, not all of which I have seen demonstrated on youtube and other web sites.
For those who like to work with antennas, I highly recommend this device. Its price is right (some good SWR meters are more expensive), and it is a fully capable device. That being said, if you do get one of these, take your time and be sure to learn how to use it.
