I had an electrician friend drive an 8' ground rod for my K9AY loop a couple
of months ago using an electric Hilti unit that hammers quite vigorously.
Lots of rock in my soil. It took him quite a while, and there were a couple
of times that we didn't think it was going to go. But it did.
This grand adventure took place line-of-sight from your location up on the
south hills of Missoula.
