Step 1. After locating the position of the satellite with the inclinometer and compass, look for
a signal on one of the satellite transponder frequencies.
Step 2. Scan back and forth in the azimuth to locate the maximum (greatest amplitude)
transponder signal (see Figure 32).
Note: Two turns of the nuts on the azimuth strut equal approximately 1° of
azimuth rotation. Approximately 4 to 5 turns of the jack input shaft is
equal to 1° of azimuth rotation.
Note: The antenna will not need to rotate more than ± 1.5° from the maximum
level or the antenna may receive a signal from a different satellite.
Step 3. With the antenna positioned at the maximum signal level in azimuth, scan back and
forth in elevation using the nuts on the elevation strut (or by driving the jack) until the
maximum (greatest amplitude) transponder signal is found.
Note: Three turns of the nuts on the elevation strut is equal to approximately 1°
of azimuth rotation. Approximately 6 turns of the jack input shaft is equal
to 1° of azimuth rotation.
