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.
NOTE: Ensure that the feed system and all electronics are installed properly before pro- ceeding.
Follow the procedures listed below when acquiring the desired satellite:
Evaluate and determine the required elevation and azimuth angles for the satellite of interest.
Loosely attach the manual actuator assembly (P/N 207882) to the elevation strut as shown in Figure
NOTE: The drain hole should be positioned downward for proper water drainage.
Ensure that the locking
Remove the two indicated
Securely tighten the remaining mounting hardware to achieve the clamping force.
Repeat the entire procedure for the remaining strut assembly.
NOTE: DO NOT loosen the Azimuth drive bearings.
Move the antenna to the desired azimuth angle by adjusting the manual actuator until the satellite signal has been spotted.
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.
