Installation and Operation Manual

1+1 Configuration with a Coupler and an Integrated Antenna :
The coupler is attached on the integrated antenna with four bolts. Two ODUs are mounted
vertically on the coupler with four latches. Each ODU is connected to its modem by a coaxial
cable.
As in most cases the coupler is not symmetrical, it is important to identify which ODU is
connected to the main position, and which ODU is connected to protection (standby) position.
The main and standby ODU positions are indicated on the coupler.
Whatever the polarization is, 1+1 the coupler is always mounted in the same position. There are
two types of coupler :
Andrew coupler : for this type of coupler the arrow on the ODU cover must be vertical
-
- Filtel coupler : for this type of coupler, the arrow on the ODU cover must be horizontal.
