[TowerTalk] Mot R36 related to NUMBER of installed ground rods

[Steve Bookout]

Jeff,

You install ground rods until either your back hurts, your wallet hurts, 
or both.

I have six 'strings' of four rods each for a total of 24 rods per 
tower.  Installed them 16 feet apart, in a one foot wide trench so I 
would never trip over them.  All are cadwelded with #4 stranded copper 
and attached to tower legs with stainless steel shim stock and stainless 
steel hardware.

I am comfortable with this installation.
