Note: Sierra Wireless recommends that the device's case or the mounting bracket be
connected to ground, which can be the battery or power source negative terminal. This
provides protection from electrostatic discharges. Do this by connecting a grounding strap
under one of the mounting screws.
In addition to the four mounting holes on the side of the device's body, there are
four holes on the bottom plate to attach the device to a mounting surface.

Vehicle Mounting

The AirLink GX Series device must be installed by qualified personnel in
accordance with the vehicle manufacturer's specifications.
When installing the device in a vehicle:
• Keep it out of direct exposure to the weather (sun, rain, etc.). The best
locations are in places like a car trunk or in a container behind the seats.
• Place it where it will not be bumped or come into contact with people, cargo,
tools, equipment, etc.
For information on connecting the power, see
page 34.

Antenna Installation

Inadequate antenna separation between the transmit and diversity antennas
creates unwanted interactions. This can cause reductions in:
• Antenna efficiency
• Transmit power
• Receiver sensitivity
