Operation
After you have completed the assembly of your antenna, you are now ready to become
operational. In order to operate the earth station antenna, you will need to direct it to the
desired satellite adjusting both the elevation and azimuth angles appropriately. The fol-
lowing procedures provide details on how to correctly position your antenna on the
desired satellite.
There are several procedures that may be used to properly acquire the satellite. Andrew
recommends that a spectrum analyzer be used. The following procedures provide
explanation as to how to use the spectrum analyzer.
While viewing the spectrum analyzer screen, a pure noise signal as shown in Figure 4-1
will probably be observed. Additionally, some transponder signals may be observed
above the noise signal as shown in Figure 4-2.
