[Hallicrafters] Storm Damages Antennas, Saturday Net Questionable

Hi guys,

I've heard the debate before but, I will stick with PolyPhaser protectors in
my shack. I have yet to find AlphaDelta brand protectors in any of the
mountaintop communication sites I frequent. PolyPhaser is the protector of
choice for those sites as well.
