Polarization adjustment is acomplished by Loosening the four 5/16-inch polarization lock down
nuts on the reflector support. See Figure 18. Rotate the reflector in polarization until the correct
polarization setting is read on the scale. From behind the antenna, rotate the reflector clockwise
for positive polarization angles and counter-clockwise for negative angles. Securely tighten the
four bolts after the correct angle is set.
Locating the satellite
1.
With elevation and polarization set and the antenna leveled and pointed in the correct general
direction, locate the satellite by sweeping azimuth.
2.
To sweep azimuth, loosen the two azimuth lock down bolts in the AZ/EL assembly. See Figure
18.
3.
Slowly sweep the antenna left and right in azimuth by hand until signal is detected. The
adjustment slots will allow ±15° of azimuth sweep. This amount should be sufficient to locate
the satellite from the coarse azimuth heading. See Figure 19.
4.
If no signal is detected, raise or lower the elevation setting in small increments and repeat the
azimuth sweep until a signal is found.
5.
After the satellite is located, turn the hex nut of the elevation adjustment rod to slowly raise and
lower the antenna until maximum signal strength is achieved. See Figure 20.
6.
Carefully move azimuth left and right until maximum signal is achieved.
