Panorama DPXA-BC-DAB Active Filter for AM-FM / DAB / DAB+ Reception

Digital radio did not replace analog broadcast — vehicles now need both, and running separate antennas for AM-FM and DAB/DAB+ wastes mounting space and installation time. The Panorama DPXA-BC-DAB addresses this as an active filter unit: it takes the broadcast feed from a compatible antenna and delivers separated, conditioned AM-FM and DAB/DAB+ signal paths to the respective tuners. Because the filter is active rather than purely passive, it can offset the splitting and filtering losses that would otherwise degrade weak broadcast signals — a real concern for DAB reception at the edge of coverage or in electrically noisy vehicle environments where alternators, inverters, and telematics equipment all generate interference. Filtering ahead of the tuner keeps each receiver looking only at its own band. Panorama specifies the DPXA-BC-DAB for use with its KF-BC-B3-L antenna, making the pair a matched system for fleet, transit, and specialty vehicle builds that combine broadcast entertainment with communications equipment. The unit ships in a silver housing at roughly 1.5 lb packaged weight, from Panorama Antennas — a UK-based RF manufacturer building antennas and signal accessories since 1947. If you are integrating radio reception into a larger antenna system rather than adding another mast, this is the conditioning stage that makes the shared feed workable.
