Radio unit and antenna should be adjusted for common polarization, as shown
below. If the LINK polarization is VERTICAL then the feeders should be remained,
as shown below:
If the LINK polarization is HORIZONTAL, use the allen key to loosen the four screws
at the waveguide port of the OSDR (do not remove the screws) and then TURN the
polarizer, as shown below:
How to change antenna polarization
refer to antenna installation leaflet.
Do not over tighten the screws. Apply maximum tightening torque 0.6 Nm.
The misalignment of slots between the movable part and the stationary part of
the radio waveguide port is intentional and does not indicate a problem.
