Antenna-Tag Orientation
Antennas need to be oriented to match the tag orientation (Figure 4-2). Antennas also
need to match the tag placement and vice versa. For example, if the tag is placed in the
center of the windshield, the antennas should be placed overhead, centered, or nearly
centered in the lane. If the tag is placed to the side of the windshield, the antennas
should be placed overhead to the side matching the tag placement, or a side-mounted
antenna should be used. There are some exceptions to this, and in the overall system
planning, any variation from this rule should be discussed with TransCore at the earli
-
est possible time to minimize additional costs for altering the lane design, especially
after construction has started. Incorrect antenna placement may render the system’s
performance unacceptable and result in the eventual and expensive refitting of
antenna and communication hardware.

tions, and Figure 4-4 shows exterior tag mounting locations.
