[TowerTalk] Liquid Electrical Tape?

[Gedas]

I double wrap with 33 or 88 and then cake on a very thick layer of RTV 
over everything extending past the tape on both ends onto the cable. 
Keeps the tape from unwrapping and forms a water tight, UV resistant 
barrier.

In over 35 years and probably 50 connections I have only seen one 
unexplained failure. I end up with almost 1/4" of RTV over the entire 
taped joint and years later, if required, it is easy to make a small 
lateral cut and peel it all off to expose the tape. RTV is inexpensive, 
I like using GE Type-II.
