Mounting considerations

Install the antenna unit referring to the installation diagram on page D-3 or D-4. When selecting a mounting location for the antenna unit, keep in mind the following points:

•Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the GPS satellite signal.

•The location should be well away from a VHF antenna. A GPS receiver is interfered by a harmonic wave of a VHF antenna.

•There should be no interfering object within the line-of-sight to the satellites. Objects within line-of-sight to a satellite, for example, a mast, may block reception or prolong acquisition time.

•Mount the antenna unit as high as possible. Mounting the antenna unit as high as possible keeps it free of interfering objects and water spray, which can interrupt reception of GPS satellite signal if the water freezes.

•Do not shorten the antenna cable.

•If the antenna cable is to be passed through a hole which is not large enough to pass the connector, you may unfasten the connector with a needle nose pliers and 3/8-inch open-end wrench. Refasten it as shown in the figure below after running the cable through the hole.
