What is the best grease to use to lubricate aluminum antenna tubes to prevent corrosion and improve conductance. It also needs to conduct electricity and protect metal screws from rusting.
The grease itself does not conduct (much). The joint pushes the grease out of the way and forms gas-tight metal-to-metal contact. The grease fills in the voids and prevents oxidation. I suspect there is a non-trivial amount of capacitive coupling going on, as well.
I use the cheap stuff, and it seems to work just fine. Find it at any big box store.
