RT-300

Product catalog summary
Overview: The RT-300 is a versatile dual-band radio direction finder designed for both emergency signal reception on 121.5 MHz and voice communication on the marine band. It is suitable for mobile operations at sea, on land, and for search and rescue (SAR) missions, serving as a navigation aid and communication tool.
Key Features:
  • Automatic operation with high receiver sensitivity for detecting weak signals.
  • Supports all 88 marine band channels (156.000 to 162.025 MHz) and the 121.500 MHz emergency frequency.
  • Automatic monitoring of emergency frequency during marine band use.
  • Displays bearing information on a graphic LCD and LED direction indicator.
  • Waterproof components (IP 67) and robust construction for reliability.
  • Integration with existing systems via NMEA, RS-232, or RS-485 interfaces.
Technical Specifications:
  • Bearing method: Doppler principle with a rotational frequency of 3 kHz.
  • Bearing accuracy: Better than ±5° RMS with a digital display resolution of 1°.
  • Frequency stability: ±2.0 ppm across temperatures from -30 °C to +80 °C.
  • Receiving bands: VHF air band and marine band, with options for UHF air band.
  • Power supply: 12 V to 28 V DC with varying power consumption based on configuration.
  • Operating temperature range: -20 °C to +60 °C, with storage temperature range of -50 °C to +70 °C.
Applications: The RT-300 is utilized by professional SAR organizations, piloting authorities, and vessel traffic services. It serves as a navigation aid and man overboard (MOB) device to ensure crew safety on commercial vessels.
Additional Information: The device features a selective squelch function to prevent false alarms, automatic squelch adjustment, and an optional internal magnet compass. It is easy to install without requiring RF cables.

RT-300-1

Elektronik GmbH IHE 2-Band Radio Direction Finder The complete solution for Safety and Communication The RT-300 is an all-purpose dual-band direction finder that receives not only emergency signals on the 121.5 MHz frequency but also voice communication on the marine band. Developed for mobile operation at sea or on land as well as for mobile landside operation, the RT-300 is an SAR and communication direction finder as well as a navigation aid all in one. The 121.5 MHz frequency is automatically monitored while the marine band is in use. The RT-300 also sets new benchmarks in terms of reception sensitivity and directional precision. Sophisticated algorithms provide fast, stable display of data.
