[TowerTalk] Grounds - - Radial Field

[Gary Schafer]

Being that you have very dry soil you can probably benefit by placing 
the ground rods a little closer together and using more of them on each 
radial. In dry soil the sphere of influence is smaller. It is as if you 
were using shorter rods. Because you will probably not get to much 
moisture until rather deep. This renders the upper part of the rod less 
useful.

I assume that you are also placing rods at the tower base? It is best to 
ground each tower leg to a rod fairly close to the tower.
If the tower is going in concrete tie all the rebar together and bring 
out leads to tie to the tower. If using J bolts be sure that the rebar 
is tied to them in the foundation.
