The Diamond MX72A is a commercial-grade, high-integrity RF duplexer precision-engineered to facilitate seamless multi-band frequency distribution across a shared transmission line. This premium coaxial splitter matrix enables operators to run dual mobile transceivers or distinct multi-frequency antenna systems simultaneously without mutual port attenuation or signal cross-talk. It serves as an essential infrastructure asset for tactical command centers, vehicular overland installations, and B2B radiocommunication hardware distribution networks looking to source authentic, low-loss filtering solutions.
The advanced internal architecture incorporates a high-isolation bandpass network configured to isolate specific frequency passbands cleanly. The low-pass channel handles HF frequencies from 1.6 to 30 MHz alongside standard VHF lines from 140 to 150 MHz, while the high-pass side covers the UHF spectrum spanning 400 to 460 MHz. This meticulous electronic design isolates active transceiver front-ends from adjacent-channel desensitization, establishing stable signal tracking and clean carrier performance even during intense high-power transmission cycles.
Built to handle rigorous operational loads, the heavy-duty design boasts substantial maximum power capacities, supporting up to 1 KW PEP on HF, 400W PEP on VHF, and 250W PEP on UHF. Housed inside a weather-resistant, shielded metal enclosure measuring a compact 46 x 25 x 57 mm and weighing just 220 g, it minimizes space requirements behind dashboard consoles or in compact base stations. Terminating in a standard low-loss male MJ (PL-259 UHF style) plug connector configuration, this turnkey duplexer ensures immediate field deployment readiness for your technical fleet equipment.
