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.

Just wondering because I am having to redo the feedline from my shack to
my tower (about 160 feet), and can avoid buying new coax by using
several pieces with PL-259s in between.
