Connecting the Antennas

This device is not intended for use within close proximity of the human body.
Warning:
Antenna installation should provide for at least a 20 CM separation from the operator.
Antennas selected should not exceed a maximum gain of 4.55 dBi in Cellular
Band and 2.85 dBi in PCS band under any standard installation configuration. In
more complex installations (such as those requiring long lengths of cable and/or
multiple connections), it is imperative that the installer follow maximum dBi gain
guidelines in accordance with the radio communications regulations of the
Federal Communications Commission (FCC), Industry Canada, or your country's
regulatory body (if used outside the US).
Your AirLink GX400 will work with most cellular antennas with an SMA connector.
Connect the primary antenna or primary RF cable directly to the antenna
connector on the back of the AirLink GX400.
Tip: When using a cable to an antenna placed away from the device, minimize the length
of your cable. All gain from a more advantageous antenna placement can be lost with a
long cable to the device.

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 into 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 options for antenna mounts:
• Magnetic roof-mount
• Through glass-mount
• Permanent mount
