It's a start. You can obtain better ground rod to earth interface by
placing the ground rods horizontally. As long as it's below the frost line
and around 2-3 feet down, it has almost the same efficiency as a vertical
rod.
Since whole books have been written on the topic, you're not going to get
the whole story in one post. I might recommend that you get a copy of my
reprint "Grounding For Amateurs". It's not only a chapter from my
as-yet-unpublished tower book but also the contains the info that I've used
for grounding talks that I have given. Send an SASE with 2 stamps to TOWER
TECH, Box 572, Woodinville, WA, 98072, for a free copy.
