VOLUME III, CHAPTER 2, ODU INSTALLATION
right offset. However care must be taken at locations where a non-standard antenna
installation is required.
The ODUs are attached to the coupler as if attaching to an antenna except that there
is no polarization rotator associated with each ODU. Rather the coupler polarization
is set to match the V or H antenna polarization using 0 degree or 90 degree coupler
interfaces, which are supplied with the coupler. Couplers are default fitted with the
vertical polarization interface.
A coupler must always be installed onto its antenna before ODUs are attached to the
coupler.
The coupler type is the Aviat Networks OCU (ODU Coupler Unit), which is supplied
as a kitset for local assembly. The kitset includes assembly instructions.
Installation Procedure
For a vertically polarized antenna proceed to step 2. For a horizontally polarized
antenna begin at step 1. Polarization setting is described in Setting the Polarization
on page 50.
1. Assemble the coupler (OCU) according to the instructions provided.
2. Check the polarization required. Change/replace the interface in accordance
with the instructions provided.
3. Remove all protective tape from the waveguide ports and check that the
ODU/coupler mounting collar, polarization rotator, coupler interface and O-
ring, are undamaged, clean, and dry. Ensure the correct O-ring is fitted for
the OCU.
4. Apply a thin layer of silicon grease around the coupler interface O-ring. A
tube of silicon grease is included in ODU and coupler installation kits.
5. Fully loosen the nuts on the four coupler mounting bolts.
6. Position the coupler so the waveguide slots (coupler and rotator) will be
aligned when the ODU is rotated to its end position.
7. Fit the coupler onto its mounting collar by inserting the bolts through
receptor holes in the collar, then rotate the coupler clockwise to bring the
mounting bolts hard up against the slot ends.
8. Carefully bring the coupler forward to fully engage the coupler feed head
with the polarization rotator in the mounting collar.
9. Finger-tighten the four nuts, checking to ensure correct engagement of
coupler with mounting collar.
10. Ensure the coupler bolt-down points are correctly seated, then tighten the
four nuts with an open-ended 19mm (3/4”) spanner.
11. To remove a coupler, reverse this procedure.

Installing the ODUs; refer to Direct-Mount ODU Attachment Procedure on page 52.
Note that when attaching an ODU to a coupler there is no requirement to first set a
polarization; the ODUs are simply attached such that when rotated into position
there is correct alignment of the waveguide slots. When fitting the ODUs ensure cor-
rect cable exit - the ODU cable must exit facing down.
