Jim,
Tnx for the info. I plan on using Amphenol #222114-10 female F-connectors in a
4x4 Carlon box. The other end goes to a relay in the box where switch in a
coil for minimum dumped power at 3775 and 3525.
73,
N2TK, Tony

Subject: Re: [TowerTalk] RG179 preparation
Hi Tony,
I've not used any of the coax this size, but I have stripped the jacket many
times using a classic electrician's stripping tool like the Klein Tools 1000.
One thing I learned, for example, is to cut the jacket using the stripping
tool's #14 notch, but use the #12 notch to pull the jacket off. This simple
technique prevents the tool from grabbing and damaging strands of the shield.
A few days ago, after K1XX posted comments about the difficulty of stripping
the center without nicking strands of it, I tried using the stripping tool to
do that. It worked fine -- looking at the result with a magnifier, it appears
to be very clean, with no "nicks."
Another observation -- in general, teflon jackets are pretty easy to strip with
a razor blade. With the larger RG400 (about the same o.d. as RG58), I nick
around the outer jacket at the point where I want the exposed shield end, then
cut longitudinally toward the end of the cable.
The nature of these teflon jackets is such that it doesn't take much of a nick
for the jacket to peel away. All of this can require some practice.
Because of the physical delicacy of the cable due to its small size, it's clear
that some very careful form of strain relief will be required. And I have no
idea about available connectors.
