[Elecraft] Coax Loss Figures

[Brett Howard]

I think I found a sheet that says its "LMR600" or at least its in a
grouping that makes me think it might be LMR600.

OD on the stuff is .591 by my measurements.

>From my calculation a 5:1 mismatch on 100 feet of LMR-400 would still
get me 75watts out the antenna at 30Mhz and things only get better as I
head down into 20 and 40 meters.
