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.

They ship UPS on the same day the order is received.. My experience is
