em-trak B350 Class B SOTDMA AIS Transceiver

The em-trak AIS B350 is ruggedised and certified IP67 waterproof and is therefore suitable for both internal and external installations. 

The B350 has an integrated, internal GPS antenna which simplifies installation on RIBs, open boats and most GRP boats. 

The unit also has a connector for an optional external antenna for installations where the internal antenna is not suitable, such as metal hulls or superstructures. 

This unit benefits from SOTDMA technology providing higher transmission power, reserved transmission slots and faster transmission rates. A simple guide to SOTMDA vs CSTDMA can be found on the following page. Yachtbits blog - sotdma-v-cstdma - Class B Transmission Technologies
