[TowerTalk] Ground rod to ground window connection?

[David Shelton]

I have an eight foot copper clad ground rod about 15ft from my ground
window, polyphaser, on the entrance to my shack from the outside. I am
looking at the best way to connect these two. I would like to use #4 or #2
ground wire. I have in the past used the 1 ½ inch ground strap that
polyphaser sells. My antenna is a Carolina Windom 160 that is not up yet as
I have recently changed QTH. 

Thanks,
David, N4IN
