8.4.1 Adjusting Azimuth
8.4.2 Adjusting Elevation
The elevation adjustment is performed in the same manner as the azimuth adjustment.
8.4.3 Peaking the Polarization
The polarization of the feed will now be peaked.
1. Adjust the azimuth and the elevation, by making ¼ turns of the adjustment nut,
and then waiting for the satellite provider to measure the cross polarization
reading. The provider will then instruct you to continue adjusting in the same
direction or to reverse the direction
.
2. Adjust the azimuth by loosening the four bolts on top of the canister as little
and as evenly between the four as possible.
WARNING
Loosening the four bolts too much, or adjusting some of them
more than others, will throw the elevation off more than
necessary.
3. After the azimuth has been peaked, make certain that the four bolts and the fine
adjustment rod are completely tightened, so that the elevation is not affected
later, after being peaked
.
1. Using the elevation rod/nut, adjust the elevation.
2. Once the elevation is peaked, make certain that the elevation rod and nuts are
completely tightened
.
1. Loosen the two screws at the feed .
2. Loosen the hose clamp on the back end of the BUC just enough that entire
assembly (feed, BUC, and LNB) will rotate freely.
3. At the direction of the satellite provider, move the feed in one direction in
approximately 1/2
°
increments, or as little as possible.
4. Wait for the satellite provider to take a measurement. The satellite provider may
tell you to continue moving the feed in the same direction, or to reverse the
direction. Continue until the satellite provider tells you that the polarization is
peaked.
