Well, WD4LST was using 100 ft at 40 M, which amounts to 0.6 to 0.8 dB
of loss depending on the feedline pedigree. RG-213 is about 0.5 to 0.6
dB at the same length and frequency, so the RG-8X looks pretty good,
particularly when you consider the cost difference. I would say at 40M
RG8X is not a bad choice, certainly not a loser. - Dr. Megacycle

    Jim your quoting loss when the SWR is 1:1. What is it when the SWR
os 5:1?

And it can get that bad easy with short antennas.
