Tips for installing a GPS on your boat

The most critical part of a GPS installation is the antenna. It should be mounted with a clear view of the sky and not in the shadow of an obstacle. Antennas should be located in areas least affected by multipath; receiving unwanted reflections from your boat structure. However, you should not mount a GPS antenna on top of a sailboat's mast. The sway of the boat is more prominent at the top of the mast, which makes the location of the antenna less than ideal, as the GPS will move as the boat tilts. If your GPS antenna or VHF receiver is in the path of the radar transmission beam, they are likely to be subject to interference. In some installations, the powerful pulses from the radar can cause serious problems and interfere with your equipment.

Your GPS may have a built-in antenna, or it may be designed with a separate antenna connected by a coaxial cable. The manufacturer should advise you not to cut this cable, as the cable length must remain the same for maximum efficiency. Follow the manufacturer's instructions.



Most recreational boats are relatively small, and even if the antenna is at some distance from the GPS, that distance may be relatively short. On a large boat, the antenna may be some distance away from the GPS display, and the readings shown on its GPS will relate to the antenna's position, not the GPS unit's position.



The GPS cable is terminated with a type of RF connector that is compatible with the antenna connector and provides a good mechanical and electrical connection. The cable can be used to connect an external GPS antenna to a GPS device or to an internal GPS antenna within the device. They may also require connection to a low-noise amplifier (LNA), as described below.

The type of cable used as a GPS cable is critical to the performance of the cable assembly, and a specific type of manufactured low-loss coaxial cable is preferable. The nature of the GPS signal discussed below means that the GPS cable length should be kept as low loss as possible. This can be achieved in a number of ways, notably by doubling the shielding of the coaxial cable and keeping the length of the cable short.



The selection of GPS cables offered here are manufactured to the highest standards of quality and provenance. All materials and manufacturing of our GPS cables comply with EU Restriction of Hazardous Substances (RoHS) regulations and Conflict Minerals regulations.
