Installing the AA3152 UTA on a Standard Gantry
For most overhead gantry installations, the AA3152 Universal Toll Antenna (UTA) is mounted on a 2- to 3-inch (5.0- to 7.6-cm) diameter pipe to accommodate various angles for lane tuning. Before installing the UTA, make sure you have the necessary items. Refer to Table 1 for a list of parts for the UTA Accessory Kit (TransCore P/N 19011-01 or P/N 19011-03).

Caution
When installing the UTA, use only the mounting hardware provided
To install the UTA
-
This antenna is typically mounted toward the driver’s side of the traffic lane. Place the UTA, top side up above the mounting pipe, and insert a U-bolt around the pole and up through the mounting bracket on the side of the antenna closest to the center of the lane.
Note: The holes in the mounting bracket are not centered. Place the bracket so the narrow side is oriented toward the edge of the radome. Refer to Figure 2. -
Place the small side of each flange washer into each of the four (4) mounting holes on the radome.
The large flat surface of the flange washer faces out. The U-bolt fits through the center of the flange washer. Place one (1) spacer, one (1) lock washer, and one (1) hex nut over each end of the U-bolt, but do not completely tighten the nuts. Repeat for the other U-bolt. Figure 2 shows the correct placement order of the mounting hardware.
Note: Use of the spacer is optional. If the U-bolt is used with a larger diameter mounting pipe, the spacer may not be necessary. -
Before tightening the nuts, rotate the antenna around the pipe so that the antenna is below the pipe. Next, angle the antenna up and toward oncoming traffic. Rotate the antenna up 15° nominal, or another specified uptilt angle from horizontal for each lane. Use an inclinometer or angle finder to verify the angles.
-
Tighten nuts with a torque wrench to 50 ft-lb (68 N-m).
-
The optional heat shrink tubing included in the UTA Accessory Kit is used for sealing the connection between the coaxial cable and the antenna.
