Mounting the A325
This section provides information on where to mount your antenna and the different mounting
options available.
Selecting the Proper Antenna Location
Proper antenna placement is critical to positioning accuracy. To select
the proper antenna location:
•
Place the antenna with an unobstructed view of the sky.
An obstructed view of the sky
may impair system performance. The GPS engine computes a position based on
measurements from each satellite to the internal GPS receiver.
•
Mount the antenna on, or as close as possible to, the center of your point of
measurement.
For example, ideal antenna placement on a vehicle is the center of the
cab roof, assuming there is a clear view of the sky.
•
Position the antenna as high as possible.
Routing and Securing the Cables
Consider the following when routing cables:
•
Power/data cable must reach an appropriate power source
•
Power/data cable may connect to a data storage device, computer, or other device that
accepts GPS data
•
Do not run cables in areas of excessive heat
•
Do not expose cables to corrosive chemicals
•
Do not crimp or excessively bend cables
•
Do not place tension on cables
•
Coil up excess cable in the cab of the vehicle or near the antenna
•
Secure along the cable route using plastic tie wraps as necessary
•
Do not run cables near high voltage or strong RF noise and transmitter sources
Mounting Options
The A325 allows for the following mounting options:
•
Magnetic mount
•
Surface mount

Improperly installed cables near machinery may cause injury or death.
