Description
The B923 is a standard transmit power (2W CSTDMA) Class B AIS transceiver that is small and lightweight, 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 lowest power consumption.
The integrated high performance VHF antenna splitter of the B923 enables the transceiver to share your existing VHF radio antenna without any loss of performance and fail-safe reliability. With built-in intelligent connectivity, integrated next generation GPS receiver & antenna and a unique FLEXI-FIT™ bracket system, safe and secure installation is simple.
