[Antennas] Grounding needs

[Alex]

.....first of all, remember that it's going to be useless as far as RF is
concerned!
>From the point of view of the DC protection, copper strap or tubing are also
useless since the skin effect doesn't come into play. Go with some heavy
gauge wire- the heaviest you can afford- for lightning protection. 
As for the RF install a counterpoise of 2 radials at least for every band
you plan to use. Try to place each pair 180 degrees from each other so that
their radiation will cancel. The other pairs can be spread quite close to
the longest ones without undue interference occurring.

I live in a 1 story home with a accessible attic.

I have an Icom AH-4 tuner mounted in the attic, and need to run a real 
ground to the 8' ground rod we just pounded in.

My question is - should the ground wire coming from the AH-4 be of a wire 
gauge of #12, or should I consider running 1/4" copper tubing?  The total 
length of the run is approximately 30'

73's
