Abstract
A method and apparatus are provided for simultaneously receiving DBS and data signals on a mobile platform using a single beam receive antenna aperture and transmitting data signals from a mobile platform using the single beam transmit antenna aperture. A single beam receive antenna aperture receives first RF signals having a first polarization and second RF signals having a second polarization, the single beam receive antenna aperture outputting output signals having the first polarization. A first RF converter down-converts the output signals to first down-converted signals having the first polarization. A second RF converter down-converts the output signals to second down-converted signals having the second polarization. The first RF signals suitably include DBS signals, and the second RF signals suitably include data services signals.
