Permanent In-Vehicle Hardware Installation D

Antenna Installation

Installation guidelines

All antennas must be spaced at least 18 inches (45.7 cm) apart. Plan the layout before drilling any holes.

A magnetic-mount antenna may be mounted on any suitable metallic surface, paying attention to the routing of the cable. However, avoid areas of high vibration. Also avoid mounting the antenna near a roof luggage rack. (The rack could block the signal.)

For permanent-mount antennas, choose a location with access both above and below the antenna-mounting surface; this is required for installing fasteners and for routing the antenna cable.

For permanent-mount antennas, use silicone sealant to prevent water leakage between the antenna base and the mounting surface.

The GPS antenna must be located outside of the vehicle with a clear view of the sky.

Choose a horizontal mounting position for the GPS antenna.

GPS antenna

You can choose between a magnetic-mount GPS antenna (E6473B option 30) or a permanent mount antenna (E6473B option 31) with the Agilent direct connect GPS/DR.

1Choose a position for the antenna that is at least 18 inches (45.7 cm) away from any other antenna.

2Route the antenna cable through the vehicle to the GPS unit.

3Secure the permanent-mount antenna to the surface with the TNC connector of the antenna cable.
