摘要:
An antenna includes a reflector having a first axis, a second axis, a focal zone that is about parallel to the first axis, and a focal point located within the focal zone. A transmit feed is located at the focal point, and at least one receive feed is located within the focal zone. The transmit feed is part of a bidirectional feed that includes an integral receive feed. The bidirectional feed transmits and receives an RF signal carrying digital information signals to and from a first satellite, such as an FSS satellite, and each respective receive feed receives a signal from satellite, such as a DBS satellite.
