MFJ Enterprises, founded in 1972 by Martin F. Jue, is a manufacturer of a broad range of products for the amateur radio market. They specialize in station accessories, such as antenna tuners and antenna switching equipment. As of 2014, MFJ was responsible for manufacturing more amateur radio products than any other company in the world.[2]
