Hi Brad,

Refer to the instructions from the PE you hired, and do that.
For my TX472, my PE (Hank KR7X) specified one ground rod/
electrode per tower leg, connected using 2/0 wire or 
equivalent, with all rods/electrodes interconnected using
2/0 wire.  I did exactly that: http://www.tinyurl.com/wa7prc-tower
A UFER ground was suggested but I didn't do that because it wasn't
in the plans from the PE.

Per NEC & NFPA, all grounds are tied into the electrical service
ground using 4 AWG, according to instructions from a licensed

vy 73,
Bryan WA7PRC

PS: Thanks Hank!
