The towers that survive the best for me are the ones that have lots of
ground rods. minimum 7 8' rods in a 35' or more perimeter. All
interconnected with large copper wire. For the ones I have installed we
run a wire 35' out from each leg. One rod at 18', one at the end. All
the 18' rods are connect around the loop (triangle.) All the 35' rods
are connected. One right at the tower that is also the ground point for
all the electronics. All the radials connect to this rod and the tower.
The theory is to get a large enough area you can supply enough electrons
so that the charge between the air and the ground is never enough to
allow lightning to form. It also provides a fairly low impedance to
ground for induced charges from nearby strikes to help reduce the damage
to equipment on your tower.

First storm of the year, early Monday morning (2-28), it wakes me up
at 4 AM. It damaged a lot of gear on a grain leg. I remember a
product that is like an upside-down, copper, "Chia-Pet" that you can
put on the top of a tower to dissipate a lightning strike in to many
smaller "hits". I am ready to buy some of these!! Anyone ever used
them, if so, do they work and where did you get them??
Thanks!!
