Abstract : The ARSR Quintuple Rotary Joint provides the Federal Aviation Agency with a rotary joint assembly with sufficient capacity to allow the operation of radar beacon equipment using the center marking technique with the ARSR family of radars. The five channels provide two L-band joints for the ARSR: one for main radar and one for sidelobe cancellation; and three L-band joints for the ATCRBS beacon: one for normal beacon, one for center marking, and one for sidelobe cancellation. The design allows for the future incorporation of additional low and medium power joints as the FAA requirements grow. The rotary joint assembly is completely, simply, and continuously interchangeable between the ARSR-1A and 1C type pedestal and the ARSR-2 type pedestal. An ARSR-1 type trial installation was both mechanically and electrically made at the Oklahoma City ARSR-1D radar site with complete success. The environmental tests were successfully made with the Quintuple Rotary Joint Assembly installed in an ARSR-2 pedestal proving both mechanical and electrical compliance with the specification in this type of antenna pedestal.
