I think it's more the installation than the choice of box. Some may be
a bit more susceptible than others, but they are more or less just a
bunch of relays.
I have had a 6-pack at the base of the tower for about 8 years now with
no problems. There are, or have been two remote antenna switches
mounted about 10 - 15 feet up the tower. Unselected positions are
grounded. That is taking into account the tower seemed to be a
lightning magnet for the first 6 years with 17 visually verified direct
hits. Yet there have been none for at least 4 years. That is at least
none that were witnessed.
All coax runs have the shield grounded at the top and bottom of the
tower. The 160, 75, and 40 meter wire antennas do not have the one side
grounded although they are grounded at the remote switches when not
selected. All lightning arresters (Polyphasers) are located at the
grounding bulkhead at the house entrance.

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.
