[NLRS] CableTV hardline

[Jon Platt]

Ditto here.   Currently using 3/4" CATV hardline on 2, 222, 432, and 902
with each run about 110' or so.   I use 7/8" 50 ohm hardline (used) on 1296
and 2304.   Like Jerry, I made my own 1/4 wavelength connector/adapters from
3/4" copper pipe and brass tubing (and a chassis N-connector) and lots of
Scotch #88 electrical tape .... systems been in use for the better part of 7
years.   Good stuff, especially if the price is right (like free).

73, Jon
