1. An apparatus for combining a first signal having a first set of channels received from a first satellite and a second signal having a second set of channels received from a second satellite, comprising:
- a combiner for summing the first set of channels into the second set of channels, wherein the first set of channels have been relocated to frequencies of one or more unused channels within the second set of channels; and
a multi-switch for accepting the summed first and second set of channels at a one of a plurality of inputs thereof, wherein the multi-switch includes a plurality of outputs and connects a selected one of the inputs to a selected one of the outputs.

Abstract
An Out Door Unit (ODU) provides the capability to aggregate signals received from more than one satellite before providing the signals to a multi-switch for selection 0by an integrated decoder-receiver (IRD). The signals from a first satellite are relocated by means of a local oscillator and multiplier to frequencies of unused channels in the signals from a second satellite. The relocated signals from the first satellite are then summed with the unused channels in the signals from the second satellite.

5. An antenna unit for receiving signals transmitted from a plurality of communications satellites, for converting the received signals, and for outputting the converted signals to a receiver, comprising:
-
a reflecting surface;
a plurality of low noise block down converters with feed (LNBFs), wherein each of the LNBFs includes an oscillator and a multiplier for converting the signals received from the satellites to a specified frequency spectrum;
a combiner for summing the converted signals from a first one of the LNBFs with the converted signals from a second one of the LNBFs, wherein the signals from the first one of the LNBFs have been relocated to frequencies of one or more unused channels within the signals from the second one of the LNBFs; and
a multi-switch, having a plurality of inputs and outputs, for accepting the summed signals from the first and second ones of the LNBFs at one of the inputs thereof, wherein the multi-switch connects a selected one of the inputs to a selected one of the outputs. - View Dependent Claims (6, 7, 8)
