8 Beacon Transmitter
• For operation up to 20m (65ft) the beam must within 5° of parallel to the
road surface.
Beam Pattern
The approximate beam pattern is shown below.
The pattern shows the limits of operation, when the beacon receiver is within
2
° of axial to the beam.
Notice that at distances greater than about 20 m (65 ft) the beam becomes
narrower which is why the angle of the transmitter becomes more critical at
longer distances.
> 25 m

5m (approx)
ID Number Adjustment
