AIS TRANSCEIVER
B300 SERIESClass B
The B300 Series is a range of standard power (2W CSTDMA) and high transmit power (5W SOTDMA) AIS Class B transceivers that are small, lightweight, ruggedized and completely water, damp, shock and vibration proof. Small in size, but powered by a sophisticated AIS transceiver engine with HF-AIS technology that empowers them with superior performance – so you see more targets and information at greater range with greater consistency and reliability.
The B300 Series benefits from an internal high performance GPS receiver with advanced redundancy. An integrated GPS antenna negates the need for an external GPS antenna in most installations.
B300 Class B2W/CS
The B300 is a standard power (2W CSTDMA) AIS Class B transceiver that is small, light-weight, yet delivers the very best AIS receive and transmit performance so you see more AIS information and targets at maximum range.
The B300 is ruggedized and completely water, weather, vibration and shock proof with the lowest power consumption of any AIS Class B in the market.
The internal high-performance GPS receiver with advanced redundancy is complemented by a unique internal GPS antenna which means that in certain installations no external GPS antenna is needed.
