How to Install the Antenna Unit(s)

1.1.1 GPS antenna unit (GPA-017S)
Install the GPS antenna unit referring to the outline drawing at the back of this manual.
When selecting a mounting location for the antenna, 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.
• 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 to
keep it free of interfering objects and water spray, which can interrupt reception of
GPS satellite signal if the water freezes.
• Referring to the drawing at the back if this manual, leave sufficient space between
all antennas to avoid mutual interference.
How to extend the antenna cable
Three types of antenna cable extensions are optionally available.
a) Antenna cable set CP20-02700
0.2m
TNCP-NJ
 Securing and waterproofing the connector
Referring to the figures in section 2.2.1 secure and waterproof the connections.
b) Antenna cable set CP20-02720 (8D-FB-CV, 40m)/CP20-02710 (8D-FB-CV, 50m)
Connect the cable the same as a) above.
Do not apply paint, anti-corrosive sealant or contact spray
to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage coating
and plastic parts, especially plastic connectors.
