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.
