So, would I be correct in assuming in this case, that it would be
"better" to have the strap bond as close to the bottom/foundation as
reasonable to reduce the "parallel conductor" distance?
In my case, there are threaded steel rods in the foundation, not a tower
section... So the bond would be made to the tower leg that is
sitting/bolted in/to a steel clevis bolted to the threaded rod. I will
give additional attention to this inward force to which you refer in the
mechanical design.... perhaps a thicker strap and more craftsmanship in
the shaping thereof is in order. <wink>.
PS - Pretty stinkin' neat to learn something new.... Here's a link that
explains the math/theory at a reasonably understandable level. <smile>

Thanks Jim!
