Ov er view Acquiring A Satellite 49 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 .
Ste p 1 Ste p 2 Ste p 3 Ste p 4 Ste p 5 Ste p 6 50 The following steps provide the procedure for acquiring a satellite. Begin by obtaining the correct Az/El pointing data for the satellite of interest. Using an inclinometer , position the antenna to the specified elevation angle.
Ste p 7 Ste p 8 Ste p 9 51 Move the antenna in azimuth to obtain a null, then move ± in elevation to obt ain a large peak signal. If not, move the antenna in the opposite azimuth direction through the peak and again move ± in elevation to obtain a large peak signal.
Ste p 10 52 With all 24 transponder signals of approximately equal amplitude appearing on the spectrum analyzer screen determine the specific antenna system and satellite parame- ters. Rotate the feed assembly as required until the appropriate (odd or even) transpon- der signals are maximized.
Subreflector Adjustment 53 Operation After the satellite has been acquired and testing has t aken place with the spectrum analyzer , the subreflector may need to be adjusted to maximize optimum performance of your anten- na. The following procedures should be followed if a subreflector adjustment is required to maximize optimum performance.

Mechanical P ar ts Inspection Local Control/Motor Driv e Controller 55 Clean mechanical part s by first removing dust, dirt, and other loose contaminants with a scraper , stiff brush (bristle or wire in the case of rust or other corrosion), or cloth or com- pressed air at 25 to 40 psi.
Antenna 56 • Check transformer for an excessive wax deposit on the surface, discoloration, or a pungent odor indicative of burning vanish denoting overheating or a total breakdown. • Check all terminal boards for broken or missing terminals and stripped threads.
57 • Operate the azimuth and elevation drives as well as the feed rotation in both the plus and minus direction from the local control/motor drive controller at least once every three months during antenna down time.
Driv e System V olta g e and Cur rent Checks Ste p 1 Ste p 2 Ste p 3 58 • Check security of antenna mounting and interconnecting assembly hardware. Be cer- tain all electrical grounding connections (including cross-axis grounding strap s) are intact and secure, not corroded or broken.
