Abstract
A receiving antenna system includes an antenna unit, a receiver unit, a down converter and a DC power/control supply. The antenna unit includes a parabolic reflector, a feed horn and an orthomode transducer, which are configured to capture, isolate, and output respective first and second polarized RF signals. The receiver unit is coupled to the antenna unit and is configured to amplify the respective RF signals and output a selected one of the respective amplified RF signals in response to a DC control signal. The down converter is coupled to the receiver unit via a transmission line and is configured to further amplify, down convert and output the selected amplified RF signal as an intermediate signal. The DC power/control supply is coupled to the receiver unit via the same transmission and is configured to produce a power/control signal that is transmitted over the same transmission line in which the selected amplified RF signal is transmitted, thereby providing power and control to the receiver unit.
