Methods and systems for mitigating interference with a nearby satellite

An antenna system for mounting on an aircraft, the antenna system comprising:

• a primary antenna for communication of a first radio frequency (RF) signal between the aircraft and one or more target satellites;
• a first transceiver coupled with the primary antenna to convert between the first RF signal and a first set of intermediate frequency (IF) signals, the first set of IF signals comprising a first receive IF signal and a first transmit IF signal;
• a secondary antenna for communication of a second RF signal between the aircraft and the one or more target satellites;
• a second transceiver coupled with the secondary antenna to convert between the second RF signal and a second set of IF signals, the second set of IF signals comprising a second receive IF signal and a second transmit IF signal;
• a first IF switch coupled with a modem on the aircraft, the first IF switch configured to selectively couple the first receive IF signal or the second receive IF signal with the modem;
• and
• a second IF switch coupled with the modem, the second IF switch configured to selectively couple the first transmit IF signal or the second transmit IF signal with the modem.
