Figure 5-8: Staggered ORT Antenna Installation

The MPR4.1 reader system and antennas 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.

• If separations are below this there is a higher risk of reports from multiple lanes for the same tag. Note

the use of the voting algorithms will correctly assign the tag to the correct lane). There may also be

some reduction in the read performance for FDM protocols.
