Thanks, Wes-- when originally considered it was looking at the moon
in terms of approaching a point source (the surface of the moon
being relatively small TIME-WISE- but the surface to the edges
being relatvly HUGE in distance , per Wavelength would allow a
distortion of a reflection. As I said , its dangerous to get me
thinking too hard (I tend to fall asleep)! Tho, hadn't considered
the (Cheezy) effect! makes me wonder if linear circular would be
the way to go, or would it distort as bad as other signals
(do to Faraday Rotation- the skewing of the signal's polarization)?
Just curious. The linear circular refers to circular yagi construction
rather than as a Helix? Or is this tilting at windmills? Jim - NN7K

Faraday rotation takes place in the Earth's ionosphere. The less than
perfect 180 degree phase shift in polarization is caused by the fact
that the lunar surface isn't a flat metallic surface but is instead,
as everyone knows, a lumpy green cheese ball.
