Number one on the list is a good tower ground bonded to the single 
point service entrance ground at the house.
MIL-HDBK-419 addresses this very well.
When this is followed, you will have very minimum problems, unless, 
you take a direct strike.
This can be minimized with static dissipators.
When was the last time you saw a FAA communications tower that took a 
hit with any damaged equipment??
