1.2.1 Mounting
Install the antenna unit referring to the "INSTALLATION PROCEDURE" at end of
manual. When selecting a mounting location for the antenna unit, keep in mind the fol-
lowing points.
• Select a location out of the radar and inmarsat beams. Those beams will obstruct
or prevent reception of the GPS satellite signal.
• The location should be well away from a VHF/UHF antenna. A GPS receiver is in-
terfered by a harmonic wave of a VHF/UHF antenna.
• The should be no interfering object within the line-of-sight to the satellites. An object
within line-of-sight to satellites, for example, a mast, may block reception or prolong
acquisition time.
• Mount the antenna unit as high as possible to keep it free from interfering objects
and water spray. Freezing water can interrupt reception of the GPS satellite signal.
