I hadn't really thought about elevated radials. I currently have 32 128(+/-)
foot radials
under the 100 foot tower although some radials have bends in them (the tower
is
70 feet from the house and about 90 feet from one side of the property). The
second tower would be more troublesome from a radial point of view for
buried
radials - more stuff in the way. I will look at the elevated radial scheme.
My main concern at this point is possible radiation pattern distortion of
the various
antennas.
