[amsat-bb] General Question on water proofing coax connectors

[W3AB/GEO]

I use the way I was trained when I worked for Motorola at a MSS.

Silicon grease on the inside, 3M 33+ tape in 2 layers on the outside. You can overwrap that with 3M 35 in the color of your choice for color coding.

Or you can use adhesive shrink tubing with the 33+ over it.
