I just watched his video...
VERY POORLY done. A true return loss of .31 dB, is anSWR of almost
infinite. With approxamatly -14dB of return loss is 1.5:1 SWR.
Cable loss has to be done with a short. He never does say what the
string of adapters is terminated with.
I'm not sure he knows how to run a VNA.
