For the rotator I use nothing. The 45G has been struck at least 17
times over the last 10 years. IE some one saw the tower take those
hits. It's a 70-80' underground run from the tower to the house and
about another 12 feet to the control box. That's roughly 190 feet of
cable. The tower and stations are grounded by a network of 33 8 foot
ground rods, cad welded to over 600 feet of bare #2. Each leg of each
tower is tied to the first ground rod about 3 to 4 feet out. The entire
system/station is tied to a single point ground. The only thing that
does not go through lightning arrestors is the rotator cable.
OTOH I would recommend the Array Solutions set up. I believe ICE also
has one.
