Abstract

Multiple systems for delivering satellite signals are described. An embodiment in accordance with the present invention comprises a receive antenna, including at least one low noise block amplifier (LNB), and a module, coupled to and proximate the receive antenna, the module comprising a multiswitch, coupled to the LNB, for directing the satellite signals received by the LNB to a plurality of outputs of the multiswitch, a plurality of tuners, respectively coupled to the outputs of the multiswitch, for tuning to a plurality of specific portions of the satellite signals in a respective fashion, the specific portions of the satellite signals selected based on commands received from a plurality of receivers, and an interface for delivering the specific portions of the satellite signals to the plurality of receivers, wherein the specific portions of the satellite signals are combined into a single combined signal and delivered to the plurality of receivers on a single output of the interface.
