1. An apparatus for improving reception in a system with multiple transmitters and receivers, the apparatus comprising:

  • a transmitter signal combining apparatus configured to communicatively couple with a plurality of transmitters, wherein the transmitter signal combining apparatus is configured to output a transmission signal based on any signals received from the plurality of transmitters;

    at least one transmit/receiver signal duplexer coupled to the transmitter signal combining apparatus and configured to provide the transmission signal to an antenna, wherein the antenna receives an incoming radio frequency (RF) signal, the at least one transmit/receiver signal duplexer further configured to provide the incoming RF signal to at least one receiver;

    wherein the at least one receiver receives incoming RF signals on at least a first frequency channel and a second frequency channel;

    wherein a first transmitter of the plurality of transmitters generates signals using the first frequency channel, and wherein a second transmitter of the plurality of transmitters generates signals using the second frequency channel; and

    a notch filter coupled between the transmitter signal combining apparatus and the first transmitter, the notch filter configured to reject a component at the second frequency channel from a signal generated by the first transmitter.
