OK, I have probed all over my yard, and it is so seriously boulder-filled
that driving a ground rod deeper than 16" is impossible. My home is
surrounded by stone walls, since everytime the house is added onto, the
builders unearth hundreds of rocks in the 20-500lb range.
So, I have decided to try using three 8' 1/2" ground rods radiating out
from my coil location, buried horizontally about 6" below the ground
surface along with a decent amount of rock salt (NaCl, not the CaCl2
kind) to help out. All connections are now 2" wide copper flashing
strips (previously #4 DC cable). As soon as the weather is nice enough
for me to move my coil outside, I will let you all know how this works.
I am still open to suggestions on what other shallow-ground techniques
might be worth while- maybe burying long and wide copper flashing strips?
