Is it better to put lightning arresters at the base of the tower or the
cable entrance at the shack or both?
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.
