For now, yes.  If you don't have the equivalent of a Goldstone dish 
with liquid helium cooled LNA and a rack of TWT amps for your uplink, 
your antenna/TX setup is unlikely to have enough gain or directivity to 
be able to use a sat much farther away than GEO.  The moon (~200K 
miles) is a bit of a stretch by ham standards, even, and L1/L2 are more 
like 46 million miles away from here, which I doubt would be usable for 
more than maybe a half dozen people that I know of ..
