Yea, then you aren't gonna want a parabolic antenna.  You would have to know
the point of aquasition, (which changes every day) and then swing across the
sky to track it.  That is dificult.  I do satellite communications with the
military, and it can be rough following some of their geosync sattys.  I
wouldn't want to even try on a polar satty.  You also will need a very clear
look at the sky.  Since the satty will be going across the whole thing, you'll
need a pretty open area for it, or a really high antenna.
