Figure 1.3 – Polarization Setting for the ODU
If antenna has a rectangular waveguide interface (13 GHz, 15 GHz, 18 GHz, 23 GHz and 26
GHz), then polarization depends on the antenna source position.
Note that ODU waveguide output must always be in the same position compared to antenna
waveguide input.
For vertical polarization, turn antenna source in order to have the large side of the waveguide in
horizontal position according to antenna manufacturer procedure. Install the ODU accordingly
For horizontal polarization turn antenna source to have the large side of the waveguide in vertical
position. Turn also the ODU in order to have coincidence between ODU and antenna
waveguides.
• 1+0 Configuration with remote mount and standard antenna :
In case of the use of a standard antenna (i.e. large antenna without SAGEM LINK F ODU
interface), the ODU is mounted on a pole with a remote mount and connected to the antenna with
a standard rectangular flex guide.
Polarization depends on the antenna source position (vertical polarization is obtained when the
big side of the antenna waveguide flange is horizontal).
