Installing and Activating AirLink GX400
Rev 1.0 Jun.11 27
GPS Antenna
Your AirLink GX400 will work with most standard active GPS antennas. Connect
the GPS antenna or cable directly to the threaded SMA connector.
If you are mounting the AirLink GX400 in a vehicle, the less the cable is wrapped
and bound together, the better it will perform. Place it on the roof, on the dash, or
on a rear panel where it has a greater than 90° angle view of the sky.
There are three antenna mount options:
• Magnetic roof-mount
• Through glass-mount
• Permanent mount.
