    • Systems and methods for providing an improved multiradio system. An exemplary system includes first and second antennas and a first receiver that receives a signal from the first antenna, filters the received signal based on bandwidths associated with a traffic collision-avoidance system (TCAS), a transponder, and a universal access transceiver (UAT). The system digitizes the filtered signal and digitally downconverts the digitized signal. A second receiver receives a signal from the second antenna, filters the signal received from the second antenna based on the TCAS, the transponder, the UAT, and distance-measuring equipment (DME), separates the filtered signal into a first signal having a bandwidth associated with the TCAS, the transponder, the UAT and the lower half of the DME RF band, and into a second signal having a bandwidth associated with the upper half of the DME RF band, digitizes the first and second signal, and digitally downconverts the digitized first and second signals.

    • Systems and methods that allow for distance-measuring equipment (DME) to use either a lower or an upper fuselage-mounted antenna. An exemplary system located on an aircraft includes an aircraft configuration data source that generates aircraft configuration information, an aircraft orientation data source that generates aircraft orientation information, a positioning system that generates aircraft position information and a component that provides DME ground station position information. The system also includes a first antenna, a second antenna and a processing device that determines if a DME signal communication issue exists with the first antenna that is based on the generated aircraft position information, the DME ground station position information and at least one of the configuration or orientation information. The processing device switches DME signal communication to the second antenna if a DME signal communication issue has been determined to exist.
