Diamond MX-610 Duplexer HF/VHF/UHF, 1.3-30/49-470MHz, 600W, SO-239

HF, VHF and UHF Duplexer for Simultaneous Multi-Band Operation

The Diamond MX-610 is a compact, high-performance duplexer covering HF (1.3–30MHz) and VHF/UHF (49–470MHz) simultaneously from a single SO-239 common port. With more than 45dB of isolation between ports and a 600W PEP power rating across HF and VHF, it is a reliable solution for multi-band shack installations. The low-pass port handles HF through 30MHz, while the high-pass port covers 49–470MHz including 2m and 70cm — with 76–120MHz available for receive only. Supplied with 35cm of 5D-2VS coaxial cable and 2× PL-259 connections.
