Abstract:
1. An apparatus capable of substantially simultaneous and non-interfering reception of a first signal transmitted on a channel from a non-terrestrial source and a second signal transmitted on the channel from a terrestrial source, comprising: a first antenna, having a primary sensitive axis directed substantially at the non-terrestrial source and at least one secondary sensitive axis directed away from the primary sensitive axis by a first angle greater than 90 degrees; and a second antenna having a sensitive axis directed away from the primary sensitive axis by a second angle less than 90 degrees; wherein the second angle comprises a second angle azimuth component and a second angle elevation angle component, and wherein the second angle azimuth component is between approximately −90 and 90 degrees and the second angle elevation component is between approximately 10 and 90−δ degrees, wherein δ describes and angle from due South to a vector from the satellite receive antenna to the satellite.
