MFJ Enterprises Original MFJ-916B 1.8-225, 350-540 MHz Duplexer - SO-239

Grate product for splitting my UHF and VHF signals from one coax to two antennas.

As expected!

Nothing rattled inside when I shook it and it works.

It was installed in a go-box with two single band radios and is working very well. Great so far!

Great item. I have an 8 element 2 meter quad and a 14 element 440 attached to a Yeasu FT857. There is one antenna port for Vhf/UHF. Previously i was using a switch which is inconvenient when working VHF contests. I have it on the unit, have checked SWR and through it n both bands it is essentially the same as on the antenna directly. I hear the Mighty Fine Junk comment on MFJ equipment so much but I have several pieces of their equipment. They cost about 1/2 of what most other vendors charge for the same item. All have served me well. This came with one anomaly, the label was on 180 degrees off. But one look told me hat to do and i relabeled it. It wasnt worth sending back. I did notify MFJ so they can see if this as a one time failure or if they have a problem.

The convenience of ordering on-line and fairly quick delivery made it easy to obtain this well known product. I use it to connect a VHF/UHF Arrow antenna to my radio while operating in a portable location for amateur radio satellite communication.

A dummy load reads about 2.5:1 SWR on 440. Replace duplexer with a barrel and the same dummy load and cables read <= 1.1:1.

I like to use the space station repeater to communicate a thousand miles away. You have to broadcast at 2meters and receive on 70 cm. This allowed my to use my dual-band Yagi antenna for both radios, and no termination is required if you arent using one of the outputs

Works just as advertised.

A very heavy solid built component in a metal box.
