Trouble is "nothing" is near the AC power common ground. Its on the other side
of the house from the shack. I'd have to figuree out a way to either dig
through a concrete patio and a concrete driveway to reach a common ground.
Looking at possibly 75+ feet either trenching through the patio and driveway or
somehow going underneath the patio, driveway and part of the house to reach it.
I do have all three legs of my tower with a ground rod for each and all three
tied together with solid #4 copper wire and three ground rods (8 ft.) in a
large flower bed outside the shack window for the rigs with a common point
ground for all rigs.. Nearly all of the Home Depots, Lowe's etc. around here
just carry 8 ft. ground rods, but we were at a Home Depot near Beaver Creek CO
a couple years ago on vacation (also picking up my new Alpha 9500 in Boulder at
Alpha's plant too since I didn't trust the freight companies) just had 10 ft.
copper ground rods. You ask the folks around the HD's and Lowe's here about 10
ft ground rods and they look at you funny.
