I have a AIS 650 with a dedicated antenna. The range for receiving other AIS transmitters is less than 6 miles in open water. Is this consider normal performance? If not what is causing this marginal performance
Welcome to the Raymarine Forum adfinger,

This is indeed normal. Unlike VHF radios, AIS transceivers, particularly Class B AIS transceivers, are designed to transmit at very low power (2W). Power and antenna height are the two primary factors limiting transmission range.
