If you need to replace the antenna, follow these steps:
Removing the existing antenna
1. Remove the transceiver (steps 1 through 6 above, beginning
on page 10–4). Be sure to remove power from the IDU
chassis power supply.
Important: A mechanical attenuator may be installed
(previously) in the antenna waveguide. If an attenuator is
installed, make sure it does not get lost or misplaced. Leave
the attenuator in the waveguide.
2. Loosen the four antenna bracket locking nuts.
