[TowerTalk] Lightning Arrestors

[Marinus Willemstijn]

Maybe this is general knowledge but could someone please direct me to some
information on lightning arrestors for my coaxial lines running to the
tower. I need some information like:

 

1)      Is there a specific distance they should be installed form the shack
or tower?

2)      Which are the most effective and best value for money?

 

Thank you in advance for your response and my apologies if this is off
topic.

 

Marinus
