EFJohnson
EFJohnson two-way radio communication products and systems date back in history almost as far as the radio communications industry itself. Founded in 1923, EFJohnson Company began with Edgar Johnson's mail-order radio parts business, and steadily grew into the engineering and manufacturing of land mobile two-way radio systems. In 1997, EFJohnson Company was sold to Nebraska-based EFJ, Inc. (formerly Transcrypt International, Inc.). and continues to engineer and manufacture the same high-quality EFJohnson brand communications equipment. Over the years, EFJohnson has built a reputation for meeting our customers' communication needs with innovative applications of radio frequency technology. We have made our mark as a leading designer, manufacturer, and marketer of conventional and trunked radio systems, land mobile radio repeaters and mobile and portable radios for local, state, and federal government as well as industrial and commercial applications.
