[TowerTalk] ground rod depth problem due to rocky soil -- solutions?

[EZ Rhino]

If that's the case, why bother with the rods at all?  Just lay *a lot* of copper strap in a trench as deep as practical and call it good?  2" wide strap is the same as the circumference of a 5/8" ground rod, but has twice the surface area because there are two sides to the strap.

I rented a Hilti demo hammer and got  about 1/3 of my rods in to the ground at least 4' -- but the  majority are only 2 or 3 feet deep because of the rocks/ledges. I  don't think I have much of a choice other than to cut the rods off  and drive the remnants into the ground field and exothermically weld  my 20 gauge copper strap to all of these shallow rods.
