The success story of QEST began with the invention of the superconducting quantum interference filter, an extremely sensitive magnetic field detector. On this basis, QEST developed a dual-band antenna for Airbus in 2005, which was successfully tested in flight. Around the same time, QEST presented itself to the connectivity industry for the first time, drawing great interest at trade shows and industry events. In 2008, QEST teamed up with the U.S. antenna manufacturer TECOM Industries to develop the KuStream 1000, a compact broadband antenna system for connectivity applications. The antenna system was delivered to various airlines, including Southwest Airlines and Norwegian Air Shuttle, among others, by the service provider, Row 44 - today: Global Eagle Entertainment. To date, QEST delivered more than 1000 antennas for this program, a number unmatched by any other manufacturer so far. Today, premier aviation system manufacturers, like Honeywell and Rockwell Collins, are customers of QEST.
