1. A method comprising:

  • receiving a signal from a first satellite at a first feed;

    receiving a signal from a second satellite at a second feed;

    producing a first signal having a first polarization and a second signal having a second orthogonal polarization from the signal from each feed;

    phase shifting the signal from each of the two feeds;

    offsetting the frequency of the phase-shifted signals from each of the two feeds; and

    combining the phase-shifted, offset signal with the second signal from each feed, respectively to reduce interference from the second satellite on the signal from the first satellite.
