Many of my AB-105 towers and much of my hardline came from a decomissioned
over-the-horizon radar facility in Whitehouse, VA near Williamsburg.
All of their RF connectors were stuffed with dielectric silicone grease as
described in this thread.
My favorite hardware supply company stocks Dow Corning dielectric sealant!

grease-like consistency. Non-melting, moisture resistant, and excellent

They ship UPS on the same day the order is received.. My experience is
that if I order before 5pm, the product I ordered is on my doorstep next
day!
