I have heard the best is 3M Scotchkote. However, I recently inspected a
coax connection on the outdoor 2 meter cable running from repeater to
antenna (on top of 500 foot building). It had been slathered with
Scotchkote after sealing with two wraps of 88, one wrap of 2228 fusion tape
and two final wraps of 88. It appears the Scotchkote was useless in the
harsh outdoor environment at 500 feet. It was dry and balled up, exposing
the 88 underneath. This connection was inspected because of high SWR at the
duplexer bottles. The problem was discovered to be the N barrel connecting
two runs of LDF50A. The first wrap of 88 with sticky side out made the
removal a snap.

Subject: [TowerTalk] Liquid Electrical Tape?
I've seen recommendations for this sort of product for as part of a strategy
sealing outdoor coax splices against moisture. I see several brands listed,
most say "UV-resistant." My intended use would be in addition to a first
double wrap with a product like Rescue Tape or 3M Mastic, and a UV
protection second wrap of Scotch 88, using the Liquid Tape for irregular
areas and parts that are hard to tape (for example, where a PL259 mates to
an SO239). I would appreciate any advice from those with experience.
Thanks and 73, Jim K9YC
