Unit
Mounting
Install the antenna unit referring to the installation diagram on page 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.
•
Be sure the location offers a clean line-of-sight to satellite.
Objects within
line-of-sight to a satellite, for example, a mast or funnel, block reception and
cause prolonged acquiring time or interruption of position fix.
•
Mount the unit as high as possible.
Mounting the antenna as high as
possible keeps it free of water spray, which can interrupt or prevent reception
of GPS satellite signal, if water spray is frozen.
•
The antenna unit GPA-018S must be grounded.
Connect ground wire of
1.25 sq or larger (local supply) between the antenna unit and a stainless steel
screw fastened to the mast.
•
The antenna unit GPA-018S must be taped.
See next page.
•
The antenna unit should be fixed to the mast as below.
Coat here with silicone sealant to
prevent breakage of the cable by
vibration.
Wrap the vinyl sheet to prevent
the breakage of the cable, and
then fix it with a hose clamp.
