Diamond MX-3000 – Triplexer (HF) (144/430/1200 MHz)


The MX-3000N triplexer can connect to a multi-band HF / VHF / UHF antenna directly to three transceivers or amateur radio of different ranges, and with just a single coaxial cable without the need for switching when changing ranges.

In this case, we are not talking only about three different transceivers. Many modern HF / VHF transceivers (eg Yaesu FT-857D and many others) have different outputs for HF bands / 2 m and 70 cm ranges. If you are using a Diamond D130 Broadband Receiving Antenna or the MFJ-1866, for admission to different audio ranges it is necessary to switch between the KB / 144 and 430 MHz outputs of your transceiver.

When using the Diamond MX-3000,  no switching is required, switching will occur automatically, directly when selecting a band on the amateur radio transceiver of your choice.


A large number of similar problems are easily solved with the use of triplexers, these devices filter the signals of the desired range and directing them to the output corresponding to the desired range.
