INSTALLATION

DOWNMAST TRANSCEIVER (CTX-A9)

WARNING

ENSURE THAT ALL POWER SUPPLIES IN THE VICINITY OF THE

TRANSCEIVER ARE ISOLATED BEFORE ANY INSTALLATION TAKES

PLACE.

Construction

18 The general construction of the downmast S-Band transceiver comprises a sheet-metal

rear plate which is formed, to include the top of the unit. This is braced by two ‘U’

sections which protrude above and below the plate, providing the bulkhead fixing points.

19 The PCBs are mounted both sides of the modulator chassis and are removed as a

complete assembly.

20 A wrap-around cover made from sheet-metal, encloses the unit and is fixed by six captive

screws. Removing the cover gives access to the front and sides of the Transceiver

electronics. Cable entry is at the bottom of the unit.

Mounting

21 Fit the transceiver to the securing bulkhead using the installation bolts supplied with the

fitting kit. Refer to Figure 1 for dimensions.
