RT-202 CrewFinder MOB Direction Finder System
Automatic MOB direction finder monitoring 121.500 MHz, alarming on distress signals and showing the transmitter bearing on an LED ring.
Description
The RT-202 CrewFinder monitors the international emergency frequency 121.500 MHz, triggers an alarm when a distress signal is received and indicates the direction of the transmitter on an LED ring, so a person overboard can be found quickly. A second frequency, 121.650 MHz, is used for training and testing.
Key features
- Doppler bearing method (3 kHz rotation), bearing accuracy ±5°
- High reception sensitivity (< 2 μV/m) and selective squelch against false alarms
- Waterproof IP67 construction, compact design
- RS-232 interface for remote control
- Operating voltage 12 V to 28 V DC; -20 °C to +60 °C
- Accessories: aluminium DCU, AU Simulator, DC/DC converter (mandatory for metal-hulled vessels)
Applications
Search and rescue, man overboard recovery and offshore operations.
