Funny thing with the HEO sats was that in some ways, they needed positioning control less than the LEO birds. The higher your orbit, the slower you appear to move in the sky. Back with some of the P3 sats in a high elliptical orbit, you could point your antennas at the bird and not have to move them all afternoon when it was at apogee. And with a geostationary satellite like P4A/QO-100, it's like your DirecTV dish - set it once and never move it again. No rotors necessary. As for the squalo vs eggbeaters question, I really don't have any experience with that type to give an accurate take on it, but it looks to be mostly a difference in pattern. The eggbeaters are more of a circular pattern while the squalo is a folded dipole and presents a more linear pattern. Focusing an antenna's beam is what tends to give it gain so with both being omnidirectional, it's probably going to be similar in results with the eggbeaters maybe handling polarity fade better.
