Vai al moduloThe Diamond MX-3000N is a professional coaxial triplexer designed for amateur radio operators who run multiple transceivers on different bands from a single antenna. It allows simultaneous operation on the HF/50 MHz, 144 MHz (VHF) and 430/1200 MHz (UHF) bands, delivering excellent inter-port isolation and minimal insertion loss.
The integrated LPF / BPF / HPF filters cleanly separate the three frequency bands, preventing mutual interference between connected transceivers. The common port features an N female connector, while the three output ports are fitted with 30 cm (5D-FB) pigtail cables terminated with a PL-259 (HF port) and N male connectors (VHF/UHF ports), ready for direct connection to your rigs.
With a maximum power handling of 800 W PEP on HF, the Diamond MX-3000N suits medium-power fixed stations as well as contest and DX setups. Its rugged construction and high-quality internal components make it a reliable accessory for everyday shack operation.
