RT-600 (formally Becker DF-517) Direction Finder

Note: Rhotheta has always been the OEM for the DF-517.

The RT-600 (SAR-DF 517) is an SAR direction finder system for airborne SAR that operates on all frequency bands used for rescue missions, including emergency frequencies 121.500 MHz, 243.000 MHz and 406.028 MHz (Cospas-Sarsat) as well as channel 16 of the marine band. Emergency beacons that operate on the Cospas-Sarsat frequency 406.028 MHz can be identified and localized. No additional equipment is required in the aircraft since the electronic direction finding components are integrated into the a ntenna. The display and control unit consists of an 80-mm round instrument, and the g raphic LCD display permits convenient viewing of localization and Cospas-Sarsat information.
