Martin F Jue founded MFJ Enterprises in 1972, after building a CW filter kit that sold for less than $10. Since 1990, the company acquired several other legacy brands within the amateur radio market, including Ameritron, Hy-Gain, Cushcraft, Mirage, and Vectronics.
MFJ became a worldwide ham radio leader in low cost accessory products. The company ceased operations in May 2024.
