The Atlantic Radio Duplexer Series features high-performance 6-cavity RF filtering networks designed for commercial, industrial, and public safety repeater stations. This specialized series consists of the AR-DUP-VHF (operating across the 136–180 MHz VHF band) and the AR-DU-PUHF (covering the wide 380–520 MHz UHF range). Acting as a critical isolation layout, each duplexer enables a dual-frequency base station or repeater to simultaneously transmit and receive high-power signals utilizing a single coaxial feedline without degrading receiver sensitivity.
This series is built for fleet technicians and wireless infrastructure engineers who need to eliminate co-site interference and receiver desensitization while avoiding the high material costs of installing multiple tower antennas. To guarantee immediate out-of-the-box functionality, professional bench tuning to your specific high and low operating frequencies is included with every purchase. Buyers must provide their exact frequency spacing requirements within the order notes at checkout so our bench technicians can calibrate the cavities for peak isolation and minimum insertion loss.
