Ah yes, the good old corner reflector... Now if you were to replace the
dipole elements with a 5/8 J-pole and suitably-sized elements, mount
them vertically on a boom, (about 6-8 Ft long?), I wonder what ERP you
would get with about 40 Watts at the antenna, (50W xmtr)?   ...Hmmm....
Not quite Moonbounce, but I'm sure it would put out a VERY respectable
signal for at least 100 miles over flat terrain.  It would be a very
interesting experiment!  If you are going to put it in a tower, you
would probably have to mount it either at the first director ahead of
the Driven Element or between there and the DE.  Comments?
