Comar T300B-S Class B SOTDMA AIS 

Supplied complete with AG100 GPS Antenna

**Offer price includes AIS programming with vessel details**

The T300B-S is a compact and rugged SOTDMA AIS Transponder with built-in Antenna Splitter, designed for the demands of the small commercial boat, fishing boat and leisure markets. It meets the Class ‘B’ (SOTDMA) standard, allowing vessels that are not required to fit Class ‘A’ units to voluntarily fit an AIS Transponder.

When connected to an external VHF antenna and a GPS antenna (not supplied), the T300B-S will transmit its own vessel position and data and receive information from other AIS vessels, shore stations and navigational aids within VHF range.

The built-in Antenna Splitter allows the unit to share a single VHF antenna with a VHF radiotelephone, eliminating the need for a second VHF antenna on the vessel and reducing installation time and cost. Additionally, the unit has an FM radio output for monitoring public service FM radio broadcasts.

The unit is initially programmed by the user with the supplied software over a USB interface. The T300B-S is compatible with a range of computer based navigation programs and chart plotters that accept AIS data sentences over a NMEA 0183 or NMEA 2000 connection.
