摘要:
An antenna (100) for satellite communications, comprising a primary reflector (110), a prime focus feed (120), a dual-reflector feed (140), and a sub-reflector (130). The prime focus feed (120) and the sub-reflector (130) are mounted for movement relative to the primary reflector (110) between a first configuration in which the prime focus feed (120) and the primary reflector (110) define a first signal path and a second configuration in which the primary reflector (110), the sub-reflector (130) and the dual-reflector feed (140) define a second signal path.
