[TowerTalk] Ground rods with jack hammer drill

[Barrie Smith]

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.
