MFJ Enterprises, Inc. was originally founded by Martin F. Jue, K5FLU, in 1972.

The company began operations in a small rented hotel room in the old Stark Hotel in downtown Starkville, Mississippi. Product marketing started in October of 1972, and the first product was a high selectivity filter that would enable a receiver to separate one Morse code signal from scores of other signals that were being transmitted over the radio airwaves.

They manufacture antennas, antenna switches, analyzers, tuners, and a myriad of Amateur Radio accessories, like morse keys, keyers, baluns, insulators, dummy loads, filters, test equipment, automatic tuners, interfaces, etc…

MFJ also owns five sister companies: Ameritron, Mirage, Vectronics, Cushcraft and Hy-Gain.
