To install antennas on brackets:
1. Remove the nut and flat washer from each of the antennas leaving the rubber O-
rings in
place.
2. Install up to two (2) omni-antennas on the upper antenna bracket as shown in
Figure 5-5 using hardware removed from the antennas in step 1.
3. Tighten the antenna nuts 6-7.4 ft-lb
(8-10 Nm) using a torque wrench.
