Wideband Airborne Radio Direction Finder for SAR & Law Enforcement, 118 - 470 MHz The RT-600/SAR-DF 517 is an advanced wideband radio direction finder system for airborne applications, capable of capturing and indicating directions to any source of an emergency signal on VHF, UHF, all 19 406 MHz COSPAS-SARSAT frequencies and all 88 maritime channels. The system can be extended by additional frequency bands to cover a frequency range from 118 to 470 MHz at its full stage of extension. For the airborne law enforcement community, RHOTHETA developed a special law enforcement version of RT-600/SAR-DF 517 which supports the LoJack Stolen Vehicle Recovery Technology, by providing direction to the target and displaying the LoJack reply code. It is also capable of tracking the Electronic Tracking System (ETS) beacons. The sophisticated software provides significantly improved tracking capability over conventional tracing equipment. It reduces search time without external support. RHOTHETA’s reliable airborne direction finders have been proved in thousands of missions worldwide under practically all climatic conditions.
