The Link-9 is designed as a replacement for the Link-8 and features an industrial design with a large, intuitive interface, removable fist microphone, built-in AIS receiver and a front mountable mechanical design for easy installation. With its integrated GPS receiver, the Link-9 has four ways to ensure GPS reliability in the event of an emergency. A GPS antenna in the face of the radio is ideal for open-air installations and the SMA connector can be coupled with a GPS-500 antenna. NMEA 0183 and NMEA 2000 connections allow the user to get GPS data from a chartplotter or from another antenna that is already in the system.
