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

Nothing rattled inside when I shook it and it works.

A very heavy solid built component in a metal box.

Just hooked up to two trancievers and two swr meters to one dual band antenna last night swr is pretty much perfect for both trancievers, both recieve fine!

MFJ products have been quality made and designed for many years. This one is no different.

Works as advertised.

As expected!

Works great. Two different radios into one antenna.

Works as advertised on 2/440 bands. Allows two high performance antennas on dual band rig.

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

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.
