Abstract
A system for distributing separate multiple satellite communication services signals to receivers at a local earth site on a single cable line. A dual satellite antenna receives the signals from two separate satellites, each of which can correspond to a respective satellite communication service. The received satellite signals are processed into two separate frequency bands. A frequency converter using frequency division multiplexing converts at least one of the received frequency bands so as to position both of the frequency bands adjacent to each other. A summer receives the adjacent frequency bands and distributes them on a single cable line to receivers so that the receivers have access to the separate multiple satellite communication service signals on a single cable line. A demultiplexer coupled to the adjacent frequency bands from the summer enables the plurality of receivers at the output of the demultiplexer lines to obtain simultaneous access to both satellite communication services distributed over the single cable line to the receiver.
