[TowerTalk] RF Surge Suppressor at Base of Tower or Shack SPG or Both ?

Rotator cables typically have no shield to bond to the tower. I use MOVs
near all of my rotators to protect the motors and potentiometers.

Jim, et al:

What about control cables coming down the tower? I just skimmed through 
the first edition of Ward's grounding book. It recommends bonding the 
coax shields to the tower, but doesn't say anything about control 
cables. Typically there is a least one rotator control cable in the mix 
and oftentimes additional control cables for array switches and multiple 
Tic ring rotators on larger more sophisticated installations. That seems 
like an inconsistency, no?
