MC-130H Combat Talon II Radome Verification System (RAVS)

Electronics Technician Brian Kirchhefer checking RF cable connections on the RAVS radome/antenna positioner. The system uses the AN/APQ-170's three main antennas--Ku-band Pencil Beam, Ku-band Cosecant2, and X-band array--in the same arrangement as on the aircraft to duplicate "real-world" radome test conditions inside the anechoic chamber. Pyramid-shaped RF absorber lining the chamber interior and covering key areas on the 9-axis positioner reduce the levels of stray electromagnetic signals reaching the test antennas. The Howland Company provided system engineering services for the RAVS design and construction team, including design of the shielded anechoic chamber and compact range, design and manufacture of a unique broadband compact range feed antenna system, human factors and system safety engineering, and technical documentation.
