Antenna Mounting Considerations

NOTICE

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 1.


    Antenna location options with callouts
  • The antenna should not be mounted where it is shaded by the superstructure of the boat 2, a radome antenna, or the mast.

  • The antenna should not be mounted near the engine or other sources of Electromagnetic Interference (EMI) 3.

  • The antenna should not be mounted near known ferrous metal objects such as a toolbox or compass.

  • If a radar is present, the antenna should be mounted above the path of the radar 4. If necessary, the antenna may be mounted below the path of the radar 5.

  • The antenna should not be mounted directly in the path of the radar 6.

  • The antenna should not be mounted within 1 m (3 ft.) of a VHF radio antenna or the path of a radar 7.
