[TowerTalk] Corrosion-proofing coax connections

[K8RI on Tower talk]

I use a bit of Silicone grease (DC-4 or DC-5) although there are other makes 
out there. Just a thin film on the surfaces will do the job. However don't 
get it on the outside surfaces as nothing will stick to it.  I also have 
used it in several cases to "flood" connectors at the top of the tower.

DC-4 was designed during WW-II to water proof the ignition connections on 
the engines of B-17 bombers to keep them from arcing at high altitude. So 
the stuff will withstand very high voltages.
