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.
