Component Installation
Horizontal Alignment
The antenna assembly must face straight ahead (azimuth) to detect objects out to maximum range traveling in the same
lane as the VORAD-equipped vehicle.
1.
Select two vehicle reference points on the vehicle centerline that are identical and symmetrical. Ensure that the
reference points are equally aligned. Items such as fenders and headlights should not be damaged or dis-
torted; otherwise, the alignment will be off.
2.
Place a long straight edge across the antenna assembly face. Center the straight edge horizontally.
3.
Measure the distance between the reference points and the face of the straight edge.
4.
Adjust the horizontal alignment screw until the two measurement points are equal.
5.
A more precise final alignment will be obtained by using the alignment software supplied with the VORAD sys-
tem and allowing the software to calculate the required alignment adjustment while the vehicle is following
another vehicle on a straight section of highway. This can be done during the road test. See Road Test Check-
Out Procedure on page 20.
