Elektronik GmbH lltlzV 4-Band Precision Direction Finder To locate and decode Cospas-Sarsat signals on 406 MHz Ok Mlonitoll On H***i|H ■SMbrJO IN***! •v ocu • 9 ^ ^ ■ The RT-500-M is a complete direction-finding solution for professional SAR applications at sea. This universal multi-band direction finder operates on four frequency bands and automatically monitors not only civilian bands (121.5 MHz, channel 16) but also military emergency frequencies (243 MHz). The RT-500-M can receive Cospas-Sarsat signals (406 MHz), provide the bearing of the source and display the content. The brilliant TFT display conveniently displays bearing information and operating parameters. The control unit and the antenna are designed for use in heavy seas. In addition, the RT-500-M is also ideal for stationary landside applications, e.g., vessel traffic services.
