Figures 5-2 through 5-4 show typical installations
of the Opticom™ GPS System Intersection Model
1010 Radio/GPS Units.
Figure 5-2 shows a Model 1010 radio/GPS unit
installed on a mast arm. The radio/GPS unit should
be mounted level and higher than the mast arm
pole, if possible. Place the unit as far out over the
intersection as possible and still provide good
coverage down the cross streets.
