Most grounding specs call for 2 or even 3 rods per run from the tower
leg. You want to have a hub (the tower) and spokes (the ground wire/rods)
The trick is connecting the wire to the rod. There are only 2 methods
that are approved by the NEC; compression and exothermic (i.e. CadWeld, etc.).
Grounding the tower is only a PART of the system - you still need to deal
with cables down the tower and the all-important building entry.
