Grounding Possibilities

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'
========================================
That 30 ft run ,whether wire or tubing could possibly radiate RF ,hence
it might be better to have an artificial ground (a series resonant tuned
circuit + a length of insulated wire) located on the loft .
The unit is tuned for maximum current .
Such a unit can be easily homebrewed ,however it can also be purchased
from MFJ (their model MFJ-931) , be it that it is to be locally
operated which might be a problem when the Icom AH-4 tuner is remotely
operated away from the loft.
