To install the check tag antenna
1. Locate the check tag antenna along the mounting pipe and insert a U-bolt around
the pole and through the bracket. Place lock washer and nut over each side of U-
bolt. Repeat for the other U-bolt.
2. For bistatic configuration, adjust the check tag antenna so it is about 2.5 cm (1 in)
from and centered on the transmit antenna. It should extend across about one
third of the transmit antenna’s width.
3. For monostatic configuration, adjust the check tag antenna so it is about 2.5 cm
(1 in) from and centered on the transmit/receive antenna. It should extend across
about one third of the transmit/receive antenna’s width.
4. Tighten the nuts with a torque wrench to 68 N-m (50 ft-lb). Tighten a second nut
over the first nut to lock it in place.
5. Slide the shrink tubing over the check tag antenna cable, but do not heat it. Leave
the shrink tubing loose until you have finished tuning the lane.
6. Connect the cable to the check tag antenna connector on the RF module. See
Figure 4-14 for the location of the RF module connectors.
Installing the IT2502 Check Tag Antenna with a
Beacon Antenna
Install the check tag antenna on the same mounting pipe as the transmit antenna
(bistatic configuration) and transmit/receive antenna (monostatic configuration). Fig-
ure 4-17 shows the correct way to mount a check tag antenna.

4. Tighten nuts with torque wrench to 68 N-m (50 ft-lb) to prevent slippage.
Tighten second nut over first nut to lock it in place.

the shrink tubing loose until you have finished tuning the lane.
