The 10 G Hz SRU may be installed with either vertical or horizontal polarization. A
label on the reverse of the SRU specifies its orientation for vertical or horizontal
polarization, and the polarization is noted in the illustrations. A rotation of 180 degrees
will maintain the polarization; a rotation of 90 degrees will change it. Both the 10 GHz
SRU and the 10 GHz BRU must be mounted in the correct (and the same) polarization
or communications will not be effective.
There are three positions that the SRU may be mounted in. Two of these result in
(vertical) polarization; one is for (horizontal) polarization. To install the 10 GHz SRU to
the 10 GHz SRU mount, follow these instructions.
1.
Three threaded studs protrude from the back of the SRU. Choose the
polarization and position you want for the SRU and insert the three studs into
the corresponding holes in the SRU mount.
2.
Install a nut, lock washer and flat washer on each bolt. Add a drop of anti-seize
compound onto the bolt, close to the final position of the nut.
3.
Tighten to the torque spec.
4.
Follow the instructions in Chapter 1 to align the SRU and the BRU.
