Overhead Gantry Mount
For an overhead gantry mount, the Orion Reader is installed with the host computer or
lane controller. The toll antenna may be attached to a 2- to 3-inch (5.0- to 7.6-cm)
diameter pipe that is supported from a gantry that spans the lanes. These components
are mounted approximately 15 to 18 feet (4.5 to 5.5 m) above the road surface. Figure
2-1 illustrates a typical overhead gantry mount.
