Comar Systems T200B-S Class B AIS Transponder with built-in Antenna Splitter - T200B-S


The T200B-S is a compact and rugged 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 standard that allows 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 T200B-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 T200B-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.

Note: this product was previously known as the CSB200-S

ALL AIS TRANSCEIVERS require a dedicated GPS antenna. The T200 units are not supplied with one, they need to be ordered separately. The Comar AG100 listed in the related products below is the recommended antenna, although an existing spare GPS antenna may also be suitable. The GPS antenna connector is a TNC threaded type, so if using an existing antenna with a BNC bayonet type, a BNC to TNC adapter will be required, also available in related products.
