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. 73, Jim KQ6EA
