[TowerTalk] ground strap width: 3' vs 6'...

Thanks for the response. I should have said "flashing" instead of "strap".

Strap is a more efficient geometry than tubing bcause it supplies a lower
impedance from its larger surface area; tubing > solid because it puts the
copper close to the skin where it does the most good. Strap will slide under
the shingles along the side of the house, so that's a good thing.

I may be showing ignorance here or do not fully understand what you are
trying to accomplish but wouldn't copper tubing <say 1/4" - 3/8">
accomplish the same thing?
