Installing the ODU on the Hybrid Coupler
1. Replace guide pin position ① of the ODU and ensure that it is located at indicator H. Apply anti-seize grease to
the screws on the guide pin.
2 Apply lubricant on gasket ⑥ of the antenna interface of the ODU. (Note: End face ② should not be applied with
lubricant.)
3. Apply anti-seize grease to the four M6 captive screws ③ of the ODU.
4. Slide guide pin ① of the ODU into guide trough ④ of the hybrid coupler, and then install the ODU onto the hybrid
coupler. Ensure that the IF interface ⑤ of the ODU faces downwards.
5. Screw the four M6 captive screws ③ of the ODU part way in and then them cornerwise.
Two ODU interfaces are available on the hybrid coupler. The main ODU must be installed on the MAIN interface of the hybrid
coupler and the standby ODU must be installed on the STD BY interface of the hybrid coupler.
