Permanent In-Vehicle Hardware Installation
• 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.
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.
1 Choose a position for the antenna that is at least 18 inches
(45.7 cm) away from any other antenna.
2 Route the antenna cable through the vehicle to the GPS unit.
3 Secure the permanent-mount antenna to the surface with the
TNC connector of the antenna cable.
