Urban canyons in large cities—a combination of tall buildings, reflective exteriors

and narrow streets—may cause varying periodic outages regardless of the antenna

type. (As will covered parking or thick overhead foliage.) The above checklist

will help installers select the optimum antenna location and antenna type.

Antenna Location Warning

Antenna location is critical for optimal GPS performance. It is

imperative that the antenna location be tested thoroughly within the

asset’s normal service area. Also, confirm that similar models of the

vehicle all accommodate the selected installation and that possible

changes during the production run have not introduced obstructions.

Use of the LED FTT tester for installation location selection is strongly

recommended (Contact CSI Wireless to purchase the LED FTT tester).

By moving the antenna as little as 2 or 3 inches an installer can

often improve the satellite coverage. Asset-Link requires up to 30

seconds for reacquiring a satellites after the antenna has been moved

during testing. Thorough testing will help avoid costly fleet-wide

changes. Typical ideal mounting locations in passenger vehicles is

under the dashboard between the firewall and passenger side airbag and

under the rear deck between the rear speakers. Speaker magnets may

interfere with antenna performance.

Asset-Link can be used in many asset management or tracking applications (not

limited to vehicles) by using different harnesses and sensors. Different types of

applications and field situations have unique installation requirements.
