Hi, Amsat-BB
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 ?
