and Connectors"
Attaching the ODU
An ODU should be installed with connectors facing down.
To attach the ODU:
1. Check that the ODU mounting collar, polarization rotator, ODU waveguide feed
head and O-ring, are undamaged, clean, and dry.
2. Set the polarization rotator for the required polarization. Refer to Setting the Polar-
ization on page 50.
3. Apply a thin layer of silicon grease around the ODU feed-head O-ring.
A tube of silicon grease is included in the ODU i nstallation kit.
4. Screw each ODU mounting bolt in approximately six turns.
5. Position the ODU so the waveguide slots (ODU and rotator) will be aligned when
the ODU is rotated to its end position.
6. Fit the ODU onto its mounting collar by inserting the bolts through receptor holes
in the collar, then rotate the ODU clockwise to bring the mounting bolts hard up
against the slot ends.
7. Carefully bring the ODU forward onto the antenna to fully engage the ODU feed
head with the polarization rotator.
8. Finger-tighten the four bolts, checking to ensure correct engagement of ODU with
mounting collar.
9. Ensure the ODU bolt-down points are correctly seated, then firmly tighten the
four bolts with an open-ended 19mm (3/4”) spanner. If a torque wrench is used, set
for a value between 18-22 Nm.
10. To remove an ODU, reverse this procedure.
Remote-Mounted ODUs

Remote-Mount Overview
The ODU 600 can be installed separate from its antenna, using a remote-mount to
support the ODU, and a flexible-waveguide to connect the ODU to its antenna:
The remote mount allows use of standard, single or dual polarization antennas.
