How Do You Install Marine GPS Antenna?
Marine Global Positioning System (GPS) units provide invaluable information to a vessels operator/navigator. GPS units rely on constant, unbroken line-of-sight (LOS) between the receiver (antennae) and satellites that are in geo-synchronous orbit around the earth. With good coverage, the GPS receiver on the vessel indicates its position on its screen with an accuracy of a few feet. In order for the GPS unit to function as expected, the antenna must be mounted properly. Determine the mounting position of the receiver unit. The receiver should be a minimum of 1 meter (3 feet) away from any obstruction that may interfere with maintaining LOS to the satellites. Radio whips, radar arrays and any metal assemblies on the roof of the vessel must be accommodated. The receiver cable should be routed to pass through a vertical surface on the pilothouse if it is not being used on an “open” boat. Drill a hole large enough to accept the rubber grommet and pass the cable through it to preserve the we
