There is provided a communication circuit (200). In an exemplary embodiment, the communication circuit (200) comprises a circuit (220) that is adapted to receive a terrestrial signal corresponding to a terrestrial frequency spectrum (504) and a satellite signal corresponding to at least one user band (506a, 506b, 506c) and to create an output signal that combines the terrestrial frequency spectrum (504) and the at least one user band (506a, 506b, 506c). An exemplary communication circuit (200) additionally comprises a circuit (300) that is adapted to reposition a satellite frequency spectrum (402, 406, 410, 414) in an unused frequency band of the output signal.
