The U.S. Coast Guard warns all mariners that certain marine television antennas may interfere with the performance of Global Positioning System receivers. The interference can result in inaccurate position information or a complete loss of GPS signals. This is a potential hazard to navigation, for both the operator of the vessel with the television antenna and for nearby boaters as the interference is not limited to the GPS equipment onboard the vessel with the antenna. In some cases, vessels up to 2000 feet away from an active antenna have reported interference. If mariners experience outages or degradation of their GPS receiver operation, they should perform an on-off test of their marine TV antenna.
