[Boatanchors] Coax cables

[Carl]

Ive been running a complete 75 Ohm system for 26 years when this town was 
first wired for CATV. RG-6 for low power jumpers, RG-11 for amp jumpers and 
around rotators and hardline to all antennas. I use it from 160M to 1296 
mHz.

Comparing equal diameters and foam density 75 Ohms has lower loss than 50 
Ohms. And it was all free.
