I use 4 gauge THHN. I recall the ARRL Antenna Book recommends 6 gauge solid
copper or larger. I want to see less than .01 ohm resistance across the
longest path. If you plan on seeing thousands of volts at any particular
point, the current flowing through the ground system can be significant.

I, too, have telco entering one corner of house (where the shack is),
tower/coax in the opposite, and power on the other side of garage.
It would take quite a bit of work (trenching, digging) to bond them all
together. But if I did do that, what material would a person use
-- #4 (or #2, or #6) copper? It would be over 100' of the stuff to connect
all the ground rods together (2 outside the shack, 2 for power, and 8 under
the tower).
