Elektronik GmbH IHE Wideband Airborne Radio Direction Finder for SAR & Law Enforcement, 118 - 470 MHz RT-600 0^0 l Clr Store Rep -o ^T\ /f£\ To .locate and decode COSPAS-SARSAT signals on 406 MHz x RHOTHETA SAR-DF 517 * ON/OFF st-soodcu ,\ 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.

• Modern and advanced widebanded direction finding system for airborne applications • Easy installation, no RF cable connection required • Extremely compact and robust antenna system • Short response time due to high antenna rotation frequency • Ultra compact display unit fits into a standard aircraft instrument • NVIS Green B compatible Display Control Unit for NVG cockpit available • Auto-scan of all COSPAS-SARSAT channels within 400 ms • Decoding/display of the COSPAS-SARSAT messages • Fast scan function of complete marine ship band • LoJack reply code decoding • Law Enforcement scan mode...
