[TowerTalk] Coax joint weather sealing

[Robert Harmon]

I have used Steve's process he described for some time and have had great results.  One additional step I do is to coat the ends of the final wrap 
of electrical tape wth black liquid tape.  This keeps the tape ends from flagging.

There are no known gloves that can be used as the adhesive qualities of the evil goo pull even the most tightly stretched powdered gloves from fingers in a second.
