[TowerTalk] 4' rods

[Rob Atkinson, K5UJ]

Seems to me that if you have enough of them and the ground is always moist 
not too far down then 4 foot rods would be okay.  Some of the commercial 
tower sites such as cell phone towers use 20 foot rods especially if they 
are in arid locations.   So whether or not a 4 foot rod is okay depends on 
where you are located.  I must say however that most parts of the U.S. would 
probably need a longer ground rod.  In most of the north the ground may 
freeze down that far in winter; in a dry spell in summer ground may dry out 
pretty deep.  I'd only consider 4' in a place like a Louisana marsh where I 
could probably get by with a railroad spike, hi.
