Please comment on the following:

What about using copper tubing as an RF ground connection? 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.

I don't know who taught you your math but 1" cooper tubing doesn't even
come close to the surface area per length of 3" copper foil. 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.
