[amsat-bb] polarization question

["Greg D." <ko6th_greg@xxxxxxxxxxx>]

Hi folks,

I should know this, but I'm not sure...

I know a circularly polarized signal switches polarity when it is reflected 
off, say, a
dish antenna.  What happens to a linearly polarized signal?  Does it matter 
if the
polarization is parallel to the reflecting surface, or cross-ways to it?

I'm wondering if a vertically polarized signal is always that way, or can 
the
various reflecting surfaces in our ilves make it go horizontal or someplace 
in between.

Thanks,

Greg  KO6TH
