The function of arrestors is to protect equipment by shorting the center 
conductor to the shield. In general, lightning arrestors should be on a 
panel that is bonded to every ground in your home and is as physically 
close to ground as practical and as close to your rig as practical. For 
a shack in the basement or on the first floor, the panel in or on the 
wall outside the shack. Also, in general, coax should be bonded to the 
tower at the top and at the bottom.

I wouldn't put an arrestor at the tower unless the antenna is connected 
to active electronics at the tower.
