Subject: Re: [TowerTalk] Hardline to F connector
Tom,
I took the figures out of the 1993 ARRL handbook. They are for solid
dielectric RG11. Foam is no doubt better. I believe your numbers.
I keep hearing "are available". Where are the 3/4" hardline F
connectors available? I've seen mostly crimp stuff for F connectors
anyhow. I suspect the crimp tool will cost more than the whole
project. Something that can be put on without a crimp tool is really
needed.
I guess it's time to call in the CATV guys to fix the ruts they left
in the lawn last year and didn't fix! Interesting that they spent $$$
running new cable under ground to a terminal post half way up my
driveway. They left the old stuff in the ground. We never have had
CATV and never will.
