[TowerTalk] Fwd: Grounding connection to tower legs (Kevin Stover, AC0H)

[Grant Saviers]

One more alternative is to use a DX Eng saddle clamp and extend the 
saddle backing plate far enough to use two hole lugs.  I made the 
backing plate out of 1/4 x 1-1/2" 6061 and wide enough for two lugs each 
side.  One clamp on each leg with 2 or 3  #6 or #2 wires to pairs of 
buried 8' rods Cadwelded.  I put some contact goop in the saddle area 
where it contacts the tower.  2" saddles for Rohn 65 are a very close 
fit.  A few dollars cheaper than the Rohn similar idea, and uses two 
hole lugs.  Aluminum against zinc is pretty benign electrochemically.
