>> ... Texas Potato Masher, the eggbeater or a turnstile ...
Polarization really hasn't been an issue for me with the FM birds - so a full-blown TX Masher might be overkill for that aspect of working the satellites.
I take my M2 Eggbeater with ground radials to shows and demos - but more for a conversation starter than anything else. Again, I am just working the FM birds. For receive, it's OK. For transmit, it just "scatters" and makes you use so much more power than you need to use.
Then again, I am working several sats with 2W or less and a handheld beam or Yagi.
A turnstile may be great mounted on a satellite - but I really think you'll appreciate the performance of a simple beam or Yagi more.
