INSTALLATION PROCEDURES
WARNING:
When installing a unit configured to be powered from a 20 to 60 VDC
source, it is important not to exceed these limits. The polarity must be observed for
proper operation; however, no damage results when the polarity of the input is
inadvertently reversed.
3.4.1
Antenna Installation
The optional antenna kit includes the following items:
•
Quadrifilar antenna with 37 dBm integral LNA
•
Threaded pole mount adapter
•
Surface mounting ring adapter
•
1"-14 to 5/8"-11 thread adapter
•
50 ft of RG-58 antenna cable
•
Various screws and washers for use in assembly
The antenna may be mounted either on a pole or flat surface, hardware to
accommodate either method of installation is provided. Figure 3-1 shows an antenna
configured for mounting on a pole.
Note: Special care must be taken when routing the cable near sources of potential
interference, such as a power lines, high frequency antenna couplers, and other
transmitting equipment.
CAUTION!
Be careful to avoid contact with overhead power lines when installing the antennas.
The mounting location should be free of any objects that might obstruct satellite
visibility within 10
o
of the horizon. Obstructions that obscure significant areas of the sky
will result in degraded performance of the unit. The antenna should be located at least
18 inches away from each other and any other GPS antenna. The antenna must be
mounted with the connector side down.
Mount the antenna as desired (pole or surface mount). At the antenna, connect one
end of the antenna cable to the antenna connector. Application of a weatherproofing
compound to the antenna/cable connection is recommended to impede corrosion.
Connect the other end of the antenna cable to the unit's rear panel connectors labeled
ANTENNA.
