[TowerTalk] Grounding on a rock hilltop

[Eric Scace K3NA]

Commercial sites run out a ground screen, typically long 'radials' of 
strap or wire.  They are anchored to the rock occasionally simply to 
keep them in place.  They form the top of a big capacitor, with the rock 
as a lossy dielectric.  Everything is referenced to this ground screen.
