ABSTRACT:
A system and method for providing independent sector mapping of signals associated with a first and second service utilizing a same multibeam antenna system is disclosed. In a preferred embodiment switch matrixes associated with each service are manipulated to selectably map sector patterns of each service. Additionally, to mitigate destructive cancellation caused by combining signals of multiple antenna beams having a signal associated with a particular sector, adjustable phase shifters and/or attenuators are provided in the signal paths.
