CP was the proposed solution to ghosting. WTTV - 4 Bloomington converted to CP
for that exact reason. Working in the field we documented the difference at a

Right you are, Paul.
However, all it takes is several wavelength's of physical separation to reap
all of the diversity gain. Of course, that's not gain in the usual sense.
Antenna diversity has been known of since the 1920s.
To get even more diversity, one could have two sets of H V
In reference to below, what would be the real advantage to using CP antennas in
addition to the V and H you'd have already? Any signal that arrives will
excite a V and/or H antenna according to it's arriving polarization, and I
don't see where CP would be a help.
Most FM broadcasters use CP.
