If you want to put shrink on a connector at the top of a tower, just use 3M cold shrink tubing. Seals the connector but no heat required…

I've used it on the back shell to coax joints on up to 1 5/8" Heliax, as well as smaller diameter coaxes. I use another piece to cover the type N joint (or heaven forbid PL 259) after it's connected, overlapping the first on both sides of the joint.. However to do this on top of a 300' tower you need either a very long extension cord or a battery operated heat gun. No, I don't even know if they exist ! This type of shrink tubing (after even 20 years) generally comes off cleanly, exposing bright connectors underneath. The removal technique involves cutting the shrink tubing longitudinally, through to the connectors, with an Exacto or other quite sharp blade, and then just pulling it apart. Properly applied, this type of shrink tubing also provides a stiffening type of support for the connector to coax joint.
