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.

So, o’wise ones; here is my proposed layout for a ground system at my new home in the dry desert at Lake Havasu City AZ. Sorry, I was unable to
drop a sketch into a post to TT - - - probably illegal anyway.
I expect to place an AN Wireless HD60/70 at the northwest corner of my
new home, not yet under construction. This will enable a 270 degree “field�
in which to arrange 20 foot buried radials with 8' ground rods at the center
of each radial and at the ends of each - - - a total of seven (7) radials. One
of these radials will be parallel to the front wall of my home.
About 30-35 feet away will be the SPG into the shack. At that point I will
have a 180 degree “field� available for another set of five (5) 20 ft
radials, two of which will be parallel to the front of the home (in line with
the one from the tower).
I figure it is OK to use these radials as part of and connected to an under-
foundation peripheral ground wire. It will be possible to connect the
peripheral wire to the buried AC ground.
So, what do all you guys think? Appreciate candid remarks without
unsubscribing.
