[TowerTalk] PL259 Cobbectors Part 2 - Murray W9EHQ

[Roger (K8RI) on TT]

Yes and it does!

Liquid electrical tape is about the only thing that works and stays.  I 
will be using it where the matching coax ts soldered in on the C3i 
antennas.  I was really surprised to find the solder joints gone on the 
144 and 440 antennas.

Epoxy works, but it deteriorates over a few years where the outer layer 
of the liquid tape only dulls a bit, which I believe is due to dust 
settling or "stuff" in the rain.  At-any-rate the liquid tape remains 
viable as long as I've had it up so far. (Not quite 12 years)

Unfortunately I have no current photos as that is now near the top of 
the tower that I can no longer climb.  I might give the 500mm telephoto 
lens a try.

I'm going to add a common mode choke of 8 turns of RG-400 on 7 cores as 
it is an end fed quarter wave fed against the tower. I've been thinking 
about a number of coils in a box switched in at the feed point to add 
length, so I can switch the resonant point down.  I believe that will be 
more efficient than just a tuner in the den, or shop.

73 es thanks.
