Garmin GPS 24xd Receiver and Antenna Installation Instructions - Page 2

Mounting the Antenna Antenna Mounting Considerations CAUTION Do not install or store the antenna near strong magnets, including speakers. A strong magnetic field can damage the antenna. You can mount the antenna on a flat surface or attach it to a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included). You can route the cable outside of the pole or through the pole. For best performance, consider these guidelines when selecting the antenna mounting location. • To ensure the best reception, the antenna should be mounted in a location that has a clear, unobstructed view of the sky in all directions . • The antenna should not be mounted where it is shaded by the superstructure of the boat , a radome antenna, or the mast. • The antenna should not be mounted near the engine or other sources of Electromagnetic Interference (EMI) . • The antenna should not be mounted near known ferrous metal objects such as a toolbox or compass. • A handheld compass should be used to test for magnetic interference in the area where the antenna is to be mounted. Your boat, motors, and devices must be on during the test. If the needle on the handheld compass moves when you hold it where you intend to mount the antenna, magnetic interference is present. You must choose another location and test again. • Mounting screws are provided with the antenna. If you use mounting hardware other than the provided screws, the hardware must be made of quality stainless steel or brass material to avoid magnetic interference with the antenna. NOTE: Test all mounting hardware with a handheld compass to make sure no magnetic fields are present in the hardware. • If a radar is present, the antenna should be mounted above the path of the radar . If necessary, the antenna may be mounted below the path of the radar . 2
