5.7 Replacing the RF PCB
1. Disconnect power from the antenna unit and the
IRD.
The RF PCB is protected within a metal enclosure that
is fastened to the antenna frame. This PCB module,
which contains the main PCB and the RF PCB, must
be removed to gain access to the RF PCB.
2. Disconnect all cables from the bottom of the PCB
module, including the roll gyro cable at the in-line
connector.
3. Using a
7
⁄16" wrench, carefully disconnect the RF
cables from the top of the PCB module.
4. Loosen the four captive screws securing the PCB
module to the antenna frame. Remove the PCB
module and bring it belowdecks for bench work.
