As has been explained here many times before, you can not "RF ground"
your coax in the sense of connecting it to earth ground. The
wavelength of the ground wire prevents a true ground from happening.

You do need a safety ground (for the AC mains) and a "ground" to your
radio chassis, but that's all. I put "ground" in quotes because it
isn't really connected to earth. The word "common" would be more
accurate, but most hams think of their chassis as "ground". So be it,
as long as the true condition is understood.
