Installing an Antenna

1. The antenna mounts on a frame using 2-inch diameter galvanized pipe clamps. For 12 ft wide lanes position

the center antenna at lane center of the defined lane. For ORT applications with 12 ft wide lanes, the

straddle antenna must be at the midpoint between the left and right antennas. Note straddle min/max

measurements in Table 5-2.

2. Orient the weep holes down, such that the radome is facing oncoming traffic.

3. Using a tilt meter, measure the road pitch and cross lane slope directly under each IAG antenna. Record

the results.

4. Using a tilt meter, align each antenna plate to the tilt angle specified in Table 5-2, in relation to the road

pitch measured in step 3 (e.g., If the road pitch is 2 degrees. and the antenna tilt must be 10 degrees,

mount the antenna at 8 or 12 degrees depending on the pitch of the road.)

5. Ensure that the height of the antenna at the center of the radiating face of the antenna as tilted falls within

the height range given Table 5-2. Please contact Kapsch Technical Service when considering mounting

the antennas outside the specified heights.

6. Adjust the roll angle of the antenna equal to 0 degrees with respect to the cross lane slope obtained in step

7. For TDM-only protocol, an ORT antenna installation may be all antennas (IAG 1 or IAG 2 or IAG 3) inline

across the roadway as shown
