Dear OM Phil, K5PC
Sorry you are so misinformed.  The GAP verttical is not a vertical per
se,
it is a vertical dipole!  Adding radials to a GAP is the worse thing you
can
do.  The recommended wires are a counterpoise for the lower bands, like
40, 80 and 160.  These counterpoise wires are not radials !  Get it !
Having said that, I tried a GAP, hoping to optimize it for 80 meters and
the
entire setup stunk.  Nuff said.  GAP has its place, but it is not a
vertical that
requires radials.  Get that through all your heads when you complain
about
the GAP.
Okay, Phil, so your friend (K2RM) said things kept falling off the GAP. 
My oh
My, there aren't too many things that can fall off a GAP, a coupla
resonant
arms which are fastened to the basic vertical via plastic connectors. 
Maybe 
your friend, K2RM, could enlighten us with a more first hand experience.
No?
Putting comments like yours on the reflector, when you do not have first
hand
knowledge just leads to speculation and bias as regards particular
antennas.
