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

Well made. Has rubber feet on bottom if youre setting it on a desk.

Does the job. Good value.

It works exactly as advertised. Simple, built heavy and it works. I use it to work Yaesu FT 2980 and FT3207 with single Diamond dualband antenna at 55 ft on tower. Can monitor both radios and transmit on either as I choose without manual switching.

Mfj tiene un problema con algunos equipos que luego de varias semanas empiezan a dar problemas con el swr

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

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.

Makes the use of separate antennas in my shack easy. I havent found a noticeable change in swr with this in line.

Excelent

Works perfect!

if you are using 2 hand helds or mobile units this will go great for your needs and for the money this is the best buy
