[ The embodiments of the invention in which an exclusive property of privilege is claimed are defined as follows:] [1.]1. A combined TCAS transponder device comprising:first and second antennas;a switch coupled to each of said first and second antennas;a transponder receiver coupled to said switch for receiving and decoding an interrogation signal;a transponder transmitter coupled to said switch for transmitting a reply signal;an air traffic alert and collision avoidance system receiver coupled to said switch for receiving and decoding a reply signal;an air traffic alert and collision avoidance system transmitter coupled to said switch for transmitting an interrogation signal; anda transmit and switch control circuit coupled for driving said air traffic alert and collision avoidance system transmitter to generate said interrogation signal, said transmit and switch control circuit further coupled for driving said transponder transmitter to generate said reply signal, and said transmit and switch control circuit further coupled for driving said switch to relay said generated interrogation and reply signals for transmission by at least one of said first and second antennas.
