Replacing the Antenna Gyro
Assembly

1. Remove the main PCB cover, as described in

“Removing the Main PCB Cover” on page 106

2. Remove the four Phillips screws, four washers,

and the counterweight from the end of the
antenna gyro (see Figure 5-8).

3. Using a

⁄

" nut driver/socket, remove the four

standoffs and washers securing the antenna gyro
to the reflector bracket (see Figure 5-8). Slide the
tie-wrap, which secures the antenna gyro cable, off
the bottom right standoff.

4. Remove the tie-wraps securing the gyro cable to

the RF cables.

5. Disconnect the antenna gyro Molex connector

from the main PCB (see Figure 5-3 on page 107).
Remove the old antenna gyro assembly.
