Tom, W8JI, has some good info on the proper use of silicone grease on his website:

For that reason, applying a sufficient amount of non-hardening silicone dielectric "grease" to the center conductor *is still important*. It fills the voids and excludes air (which will contain moisture) from the assembled connector. And if we run the legal limit through F connectors (which I and other hams have done for years), silicone dielectric compound can help prevent arcing inside the F connector. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband
