Gogo 5G Aircraft Antenna Receives STC and PMA February 24, 2022 BROOMFIELD, Colo. – Gogo Business Aviation (NASDAQ: GOGO) has received Supplemental Type Certification (STC) and Parts Manufacturer Approval (PMA) from the FAA for its 5G aircraft antenna. “Receiving STC and PMA for the 5G antenna marks the next important milestone in the development of Gogo 5G,” said Sergio Aguirre, president of Gogo Business Aviation. “Our team has been hard at work to bring Gogo 5G to life and we remain on track and on budget to launch service in the second half of 2022.” The STC for the multiband belly-mounted 5G antenna was completed by Duncan Aviation on its company-owned Citation 560XLS. In November, Gogo also announced that Duncan Aviation is working to complete the first-article STC for the onboard 5G system. Gogo's authorized dealers and OEM partners are actively pursuing multiple STCs that will certify the Gogo 5G system for installation on more than 30 business aircraft models. Gogo 5G is expected to deliver ~25 Mbps on average with peak speeds in the 75-80 Mbps range and has been designed to deliver high throughput with very low latency to address the increasing demand for data-heavy interactive services like video conferencing.
