[HCARC] Hex beam Antennas

[Gary and Arlene Johnson]

Dale,

I am not advocating in favor of replacing Yagi's with Hex Beams.  It just 
seems like an interesting antenna that might "have a place in a Field Day 
scenario".  As for what I heard - this guys Hex Beam was performing better 
than HIS yagi was, at supposedly 93 feet.  Do I know what kind of Yagi and 
was it really at 93 feet - Nope - haven't been to his house in Alabama (and 
with my dislike of traveling - probably won't).

Just something that was interesting and the Reflector has been all too quiet 
all summer.
