Diamond MX-3000 Triplexer HF/VHF/UHF/1.2GHz, 1.6-160/350-500/850-1300MHz, 800W

Three-Band Triplexer for HF, VHF, UHF and 1.2GHz

The Diamond MX-3000 is a precision triplexer that simultaneously splits or combines three separate frequency bands — HF/VHF (1.6–160MHz), UHF (350–500MHz), and 1.2GHz (850–1300MHz) — from a single Type N female common port. With more than 55dB of isolation between all three ports, it provides clean separation for demanding multi-band installations. Whether you are running separate HF, 2m/70cm, and 23cm antenna systems from a single transceiver output, or combining multiple radios into a shared antenna, the MX-3000 handles it with minimal insertion loss. Supplied with 35cm of 5D-2VS coaxial cable.
