Strong Legacy

GatesAir connects a legacy of innovation with a vision for the future. GatesAir has been an innovator in over-the-air broadcasting for 100 years, and today offers the industry’s broadest portfolio to help broadcasters deliver and monetize content. The company’s roots date to 1922, when Henry C. Gates founded the Gates Radio and Supply Company. Henry’s son, Parker Gates, quickly established the company’s reputation as a visionary, responsible for industry firsts in audio and electronics. These innovations laid the foundation for groundbreaking over-the-air radio and television transmitter designs that continue to this day.

Upon the sale of Gates Radio to Harris Intertype Corporation in 1957, Gates Radio had become a major supplier of audio consoles, turntables, and AM/FM shortwave radio transmitters and accessories. Moving forward into the next several decades, Harris Corporation was responsible for several groundbreaking developments in over-the-air TV and radio, including the world’s first solid-state AM transmitter in 1974; and development of the “Mod Anode Pulser” for UHF TV transmitters in 1981, a simple technique that reduced power consumption in UHF TV.

The company followed these foundational innovations in the 1990s and 2000s with the world’s first digital FM and HD Radio exciters (1993 and 2002), and the first DTV transmitter to hit the airwaves (WRAL-TV in Raleigh, North Carolina, 1996). In 2009, Harris Corporation’s Broadcast Communications Division broke the paradigm for high-efficiency TV and radio transmitters with PowerSmart®, a green architecture for reducing transmitter size, weight and energy consumption.

In May 2019, GatesAir announced its purchase of ONEtastic S.r.l., a leading provider of television and digital radio transmission systems based in Brescia, Italy. The addition of the ONEtastic catalog to GatesAir's Maxiva product line expanded its offerings and innovative capabilities. ONEtastic's strength in high-efficiency, low-power TV and DAB radio transmitters also helped GatesAir better address the needs of large-scale over-the-air networks worldwide. The acquisition also strengthened GatesAir’s growing presence and visibility in Europe.
