I use a single ground rod at the base of the window where all arrestors are
located on an aluminum bulkhead. They are all Polyphaser's. The bulkhead
has a #4 stranded copper wire bolted to the bulkhead and running to the
ground rod, connected there via standard rod connector as used by power and
phone company. Yes, the ground rod is cadwelded to the tower ground system.

Subject: [TowerTalk] 11th hour grounding question
OK, I am on the home stretch here, as far as my new tower's grounding system
goes, but now what do I do?
I have a properly Cadwelded ring around the tower, six buried ground rods,
and a conection back to the shack all Cadwelded to the house ground.
But, I have one more little step. I have to connect the lightning arrestors
to the ground system. I have wire that is going into the control boxes for
the arrestors also Cadwelded to my aforementioned ground, but how to
actually connect? No Cadweld here.
I have the KF7P boxes and Array Solutions arrestors. But, thees arrestors
apparently want me to simply screw some sort of copper wire on, tight, with
a nut and a washer.
I then would bring (presumably bare) copper wire down to ?? something and
then connect that something to the wire coming up from the main Cadwelded
ground.
Do I just buy "the usual" ground strips from Home Depot and screw them on
with screws (friction)? Or, is there something better I need to be doing
here? I have a similar question for my MOV boxes, which seem to simply have
steel grounding plates that are at least as much about attaching themselves
to something as they are about a solid ground.
Hate to screw it up at the 11th hour.
