Here is a solution from a very old QST, and all I can say is it works
for me. My shack is on the 2nd floor and I run several rigs w/ amps . I
was having RF everywhere until I tried this:
- Run coax ( RG-8 or similar) from rig to a real good ground . Put a
.01 cap across the shield and center conductor at both ends. Cap needs
to be 2KV or better. You will be using the center conductor as your
connection to rig and the ground rod.You should also use an ATU as
mentioned in an earlier reply.
