About the Header
For more than 70 years, Southwest Research Institute has developed signals intelligence technology, designing, fabricating, testing and supporting airborne, land and maritime direction finding antennas. We continue to expand radio frequency and signals analysis capabilities and facilities, completing a new antenna testing facility in 2021. The antenna test range featured on the cover includes two 70-foot towers in a 200-acre field to simulate land-based towers and the main masts of naval vessels at sea.
