3.3.11.1 PSR Coaxial and Electrical Cable - Figure 3-10.
All connectors have identification labels which correspond to the respective cable assembly. Use the
hangers provided to secure the cables to the feed support structure. In addition to the hangers, use
Cable Ties (item 10) as required to tie off cable assemblies. When securing cables, allow for
sufficient bend radius and ensure that no bending stress is placed on the connectors. Make the
following connections:
a. Connect CAX1 (item 4) from the type >NT= transition at the rear of the High Band Feed (lower feed
horn) to the connector labeled >CAX1' on the Polarization and Beamswitch Control box.
b. Connect CAX2 (item 5) from the type >N= transition at the rear of the Low Band Feed (upper feed
horn) to the connector labeled >CAXT on the Polarization and Beamswitch Control box.
c. Connect CAX3 (item 6) from the Channel 3 connector on the Rotary Joint to the connector labeled
>CAX3' on the Polarization and Beamswitch Control box.
d. Connect Control Cable CA1 (item 1) from the 15 pin Low Beam (upper) polarizer connector to the 6
pin connector labeled >CA1' on the Polarizer and Beamswitch Control box.
e. Connect Control Cable CA2 (item 11) from the 15 pin High Beam (lower) polarizer connector to the 6
pin connector labeled > CA2' on the Polarizer and Beamswitch Control box.
f. Connect Control Cable CAS (item 2) from the C2 connector on the Rotary Joint to the connector
labeled >CA5' on the Polarization and Beamswitch Control box. Both are identical 14 pin connectors.
g. Connect Control Cable CA4 (item 3) from the Cl connector on the Rotary Joint to the connector
labeled >CA4' on the Polarization and Beamswitch Control box. Both are identical 5 pin connectors.
h. The AC Junction Box (para. 3.3.8, Fig.3-10) included cables designated as CA3. Connect 6 pin
connector to the connector labeled CA3 on the Polarization and Beamswitch Control box and the 9
pin connector to the C3 connector on the Rotary Joint.
i. To provide additional moisture seal and help preventing loosening of connections from vibration, all
connectors must be wrapped with weatherproof tape provided in the Connector Weatherproofing Kit
(item 13). Use the following procedure to wrap each connector:
