Overview

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.

Applications

  • Commercial boat fishing boat and leisure markets
  • Meets the Class ‘B’ SOTDMA international standard

Pocket and ability to hook my speaker to
Size: 32, Color: Black, Size: 32, Color: Black
I can't believe how comfortable they are and I'm very happy with all the pockets in the shorts. I bought the black as it my favorite color but will definitely be ordering all the colors available as they can be used as dress shorts.
