Polarization Loss?

Interesting thought. That means that with two antennas,
one clockwise and one ccw, you could adaptively mix the
two signals to cancel the 1st reflections.
A c-pol receive antenna having the same rotation sense as a direct-
path, c-pol radiated wave will reject reflections/re-reflections of it
from any odd number of surfaces. The first-surface source usually is
the dominant source of reflections.
However if the rotation sense of a c-pol receive antenna is opposite
that of the transmit antenna, then it will reject the direct path
signals and receive only those reflections of it.
