[TowerTalk] Relay Box on Tower

[rfman45]

  I am looking to install a remote antenna relay switch box (Rat Pack, etc.) to choose antennas at my tower. I would like to hear your opinions especially on the service life of them versus lightning-induced surges, etc. Is there anything you've found that I should know? I lost one a couple of years ago and I'm looking to avoid that as best I can.  I lurk here 99% of the time and appreciate the group's generosity in sharing knowledge.    Thank you in advance for any thoughts you can offer.                                                             Mike  W2LO
