[amsat-bb] antenna question

Are there any antenna designs that use predominantly rotating
sub-reflectors and a reflector for tracking LEO birds, in contrast to
rotating the main antenna structure on booms in the AZ-EL directions ?
I am aware of multi-LNB antenna arrangements, thought it would be
interesting to find out ways to keep a fairly large reflector constant
on the ground and use a smaller steerable sub-reflector or horn feed
to aim the beam ?
Any ideas ?
