Figure 5-6: Staggered ORT Antenna Installation

The JANUS reader system and antennas in the lane kits are optimized for applications using 12 foot

lane widths. The antenna placement requirements and support for this and other lane widths are as

follows.

• The lane centerline is the mid-point between the lane markings.

• The antenna bore site should be on the lane centerline and lane markings.

• Physical lane widths below 12 ft. (3.66 m) are not an issue provided the separation between lane

centers is 12 ft. or greater.
