em-trak B953

AIS Class B953 Transponder

AIS Class B953 Transponder is a high transmit power (5W SOTDMA) 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 – all achieved with the least power consumption.

AIS Class B953 Transponder has an integrated VHF antenna splitter which enables the transceiver to share your existing VHF antenna without any loss of performance. With built in intelligent connectivity, integrated next generation GPS receiver & antenna and a unique FLEXI-FIT bracket system, safe and secure installation is simple.
