I still use some 4:1 adhesive lined heat-shrink on difficult connectors, like the 3GHz 450 antenna ports because they're so awkwardly close together. But I stopped using it on the radio side because we've had so many 450 APs leak and it's a pain in the ass to take apart. 450i is a different story. That should have no issues with hot or cold shrink with the bulkhead design they used. So much easier.

The silicone-rubber tape I use is DSG/Canusa CTB-15. You can find it for about $12, IIRC. It's UV stable. I've never put any vinyl tape over top. Had connections sealed with the stuff in the field for over 10 years, and other than bird shit, it looks like it was applied yesterday. Cut it open and the connectors are still shining like new. And no mess.

Well, only a little bit to keep the end from flapping or adjusting to any other irregularities. It otherwise forms a waterproof bond to itself.

Gotcha, thanks. I assume you also wrap it in electrical tape after the silicon?

    Know who it is made by?

        Is that like the 3m rubber splicing tape?

            Cold shrink is good. But i am with Mike. We use silicon
            tape on everything now. Easier to work with putting on and
            taking off. Times Microwave WK-S-2 I think is the part
            number we order.

                Is cold shrink sealing effective for weather
                protecting an N connector on a tower radio?  I'm
                trying to seal up the connectors on an eNB and am
                running into space constraints with the electrical
                tape / mastic / electrical tape method.
