I agree with Mark 100%.
I've been using my 'terrestrial' M2 antennas on the satellites for
years. The GulfAlpha "Easy Satellite" antenna I use for Field day is
also linearly polarized, and works very well.
Fades? Sure I get them, but most of the time it's only for a few
seconds, and while a bit annoying it's not a show stopper.
