Dave,

Why would you need an RF ground? Are you feeding a long wire 
antenna against the ground in the shack?  Or perhaps you 
have an end-fed Zepp or Windom?

As Martin just said....if the feedlines are installed 
correctly, you have properly designed antennas with good 
feed systems, your equipment is proper, and you have no 
common mode currents on the feeders there isn't need at all 
for a RF ground. I don't use one, all of my grounding in the 
shack is for lightning and safety.
