  My experience has been quite different Clint.  There have been times when I've noticed a drop in signal strength, rotated my Arrow antenna 90 degrees, to find the signal strength back up.  I had been told earlier by an experienced sat op of the FM birds that there would be shifts in polarization during passes that I would have to correct for.  It appeared to me his advice was correct.
