1. A device for communicatively coupling a plurality of transmitters and receivers to a plurality of antennas, comprising:

  • a plurality of transmit ports adapted to be connected to respective transmitters;

    a plurality of receive ports adapted to be connected to respective receivers;

    a plurality of antenna ports adapted to be connected to respective physically remote, duplexed antennas, each antenna being located in and providing coverage to a different zone;

    first coupling means having inputs connected to respective transmit ports and outputs connected to respective antenna ports, for combining individual transmit signals received at the transmit ports to form a combined transmit signal and outputting in parallel the combined transmit signal to each respective antenna port; and

    second coupling means having inputs connected to respective antenna ports and outputs connected to respective receive ports, for combining individual receive signals received at the antenna ports to form a combined receive signal and outputting the combined receive signal to the receive ports,wherein said device passively couples the plurality of transmitter and receivers to the plurality of antennas for transmission of radio frequency signals therebetween.
