VOR High Performance Balanced-Loop Set/Single Output Combiner with single output combiner is designed primarily for large airframe turbo-jet aircraft installations where the VOR and glide slope signal reception is provided by separate antennas. Antenna set provides for reception of VOR, area navigation and localizer signals when mounted high on the aircraft vertical stabilizer. Features low drag "knife-edge" aerodynamic shape, rugged mounting base, horizontal/omnidirectional pattern, wide band/high efficiency/high gain electrical performance, DC grounding for lightning protection and "industry standard" 8-hole mounting. Complete set includes a pair (2) of blades, each with single BNC connector output, two coax interconnect cables and a CI 120-3 signal combiner with single BNC connector output. Set provides for a single cable routing to the avionics installation for NAV 1 receiver. Use the CI 502 diplexer for dual VOR operation with NAV 1 and NAV 2 receivers.
