Polarization setting :
- Coupler : ODUs are mounted vertically on the coupler. Depending on the coupler type the
arrow on the ODU cover must be horizontal (Filtel) or vertical (Andrew).
- The polarization can be adjusted from turning the coupler polarizer from 90 degrees
(Andrew) or by replacing polarizer (Filtel). Refer to coupler supplier instructions.
- Antenna : If the antenna has a rectangular waveguide interface, rotate antenna source to
have the wanted polarization. Make sure that polarizations are the same for the antenna
and for the coupler.

• 1+1 Configuration with a Coupler Remote Mounted and a Standard Antenna :
The coupler is attached on the remote mount and connected to the standard antenna by a flex
guide.
The two ODUs are vertically mounted on the coupler, with the arrows in vertical (Andrew) or
horizontal position (Filtel). Each ODU is connected to the IDU with a coaxial cable.
