Hi Gene
As I understand it you don't want a direct lightning hit to go through
the tower base as it might crack the base and cause the tower to colapse.
By driving other ground rods and connecting them to the tower legs above
the base you will divide the current away from the base protecting it.

Subject: Tower grounding.
Fellow reflector members:
I know that a tower mounted ON, not in/through a
concrete base needs a grounding cable. But in
the case where the tower, Rohn HDBX-48 in my
case, will be mounted onto metal stubs (BXB-8)
that go through the concrete and are touching
the ground underneath, is it still necessary
for an additional grounding cable?
I've got a feeling that there are some codes
governing this but I just don't know where to
turn to get them. The Rohn manual for the
HDBX-48 doesn't specify anything in the way of
grounding.
Thanks in advance for advice!
Gene
