摘要：An apparatus for satellite communication may include a reflector configured to redirect electromagnetic energy. Each of multiple feeds may be positioned at a predetermined location with respect to the reflector. A feed-switching mechanism may be configured to selectively activate for use at least one of the multiple feeds. A steering mechanism may be configured to steer the reflector such that a focal point of the reflector approximately coincides with a position of an activated feed of the multiple feeds. The reflector may be mechanically independent of the plurality of feeds and the feed-switching mechanism.

主权项：1. An apparatus for satellite communication comprising: a reflector configured to redirect electromagnetic energy; a plurality of feeds, each positioned at a predetermined location with respect to the reflector; a feed-switching mechanism configured to selectively activate for use at least one of the plurality of feeds; and a steering mechanism configured to steer the reflector such that a focal point of the reflector approximately coincides with a position of an activated feed of the plurality of feeds, wherein the steering mechanism comprises a vertex positioning mechanism including a pivot coupled to an edge of the reflector, and wherein the vertex positioning mechanism is configured to steer the reflector in a vertex configuration around the pivot.
