Pro tip: One wrap of electrical tape on your coax connector before you crimp it

I've been installing cable for about 8 years now and always had issues with signal loss on outdoor runs. A old timer taught me to put one single wrap of electrical tape around the connector before crimping the F connector on. I tried it on 15 jobs last month and my signal readings stayed above -5 dBmV even after a rainstorm. But I've also heard guys say the tape traps moisture and causes corrosion down the line. Has anyone else tried this or have a different trick for keeping water out of outdoor connections?

Skip the tape and use silicone grease on the threads instead, keeps moisture out way better long term.

Heard a similar thing from an old boat mechanic, @king.derek, said grease keeps the threads from seizing up too.
