You have to be careful with those gasfet lightning arresters because they'll 
open up if there's a nearby lightning strike and remain open until they are 
replaced.  I actually had that happen to me when I was the field day trustee 
for an operation from the emergency operations center in Prince George's 
county and we couldn't get to the antennas because the Executive Director's 
office was locked So we ended up blowing up the eoc's radio and we had to 
set everything up with a different rig and antenna configuration so we could 
continue to operate.
