Marine GPS antenna
An external marine GPS antenna is a device that enables you to receive GPS (Global Positioning System) signals when you're at sea or on a river. It is generally used with navigation devices such as boat GPS, navigational plotters or depth finders. Find external GPS antennas from Garmin, Furuno, Simrad, Humminbird to improve the range of your built-in GPS, or to add GPS functionality to a VHF or other compatible device.
