This NanoVNA has helped me debug many antenna problems.  But now that everything is working, I don’t need it any more, so it should find a new home.  It’s rated to 4 GHz, and this is the Plus4 version, which cleans up the signals in the GHz region and significantly reduces drift vs. the original V2.

Note: I bought the VNA directly from Tindie; it’s not an unauthorized knockoff.

Included with the VNA are the calibration heads (short/open/50 ohm), stylus, two SMA male-to-male jumper cables, and a F-F SMA adapter.
