[TowerTalk] Antenna/Tower Grounding (Lightning Protection)

[Les Kalmus]

In my case, (building a new house) the radio cables will enter below 
grade on the other end of the building from the shack. The main 220V 
supply to the house will be close to the shack. I intend to have a 
perimeter ground system with ground rods at either end entry point and 
in the middle, all Cadwelded to #2 solid copper connecting everything. 
The electrical, CATV, phones, etc. plus shack ground will all connect to 
this system at one end. Antenna cable entry will be at the other end.
Should be OK, no?

So I have four Hoffman enclosures which are mounted next to each other and tied together is wide copper strap.  These are mounted along the back of the deck which is also right in front of the shack entrance.  One foot beneath these boxes are three ground rods which are all tied together similarly and the boxes then are grounded to this SPG system.  So my SPG is as you describe a place.
