Since the current flows on the surface, a tube seems to be the most space efficient way to get a large surface area. PI*R seems to say that a 1" copper tube would be as effective as a 3" or so copper foil. Any thoughts? Thanks, Dave. "Bruce in Alaska" wrote in message ...

It isn't the DC amps that you need to worry about it is the Impedance of the connection between the RF Ground System and the Ground stud on the Antenna Tuner. Lower impedance better Rf Ground. It is the Ground that makes the Antenna work. Bruce in alaska -- add a 2 before @ |
