4 AMG1000ALx-VCM Light Duty/Passenger Vehicle Kit Installation Guide
Identify the best location for installation:
Before the wiring harness, AMG base unit and antenna are installed, it is strongly
recommended that the vehicle cab is inspected for potential installation locations and an
installation plan is devised. Keep the following information in mind when locating a suitable
install location and plan:
1) The AMG base unit may not be installed any further than 9 feet away from the vehicle’s
interior fuse panel.
2) The external antenna (included in AMG1000ALx-VCM kits only) may be installed up to
15 feet away from the AMG base unit.
3) Antenna reception is critical for effective AMG operation, therefore the antenna must not
be obstructed by metal objects. Optimal antenna orientation is shown in Figure 3.
Figure 3: Optimal Unit Orientation
The external aerodynamic antenna mounts outside the vehicle cab (generally on the roof).
For optimal reception, the antenna should be mounted on a horizontal metal surface as
shown in Figure 3 but not be obstructed by surrounding metal objects. The mounting
surface should be no thicker than ¼”. To mount the antenna, a hole ¾” in diameter must be
drilled or punched into the surface. For roof mounts, remove any material on the underside
of the cab before creating the hole. In order to secure the antenna mounting, it is necessary
to also have access to the underside of the hole (normally inside the cab). The gasket
attached to the underside of the antenna acts as a moisture seal which prevents moisture
from entering the vehicle.
WARNING! The external antenna must only be used with the supplied cable [type=RF-195,
length=15 feet (4.5 meters), minimum attenuation=2.25dB] or similar cable with minimum
attenuation of 2.25dB. This is necessary to limit the antenna gain to no more than 3dBi in order to
comply with FCC part 24.
