#379: How to measure coax loss using a NanoVNA

This video shows how to setup your NanoVNA to measure coax loss using an S21 measurement on a VNA. I show the setup and calibration process, as well as some actual measurements of a few lengths of RG-174 and RG-316 coax that I use for my portable (POTA) HF operating.
