[TowerTalk] lightning arrestor placement

[Jim Hoge]

Greetings,
 
What is the consensus for feedline lightning suppressor/arrestor placement, upstream or downstream of a remote antenna switch? The antenna feedlines will be coming to a common point (the remote antenna switch) outside the house from all over the yard. It seems that to be most effective, each feedline would have an arrestor before being connected to the remote antenna switch. However, placement after the switch would reduce the number of arrestors and the cost. The controll wires for the switches and rotors will also have arrestors.
 
Thanks,
