Page 10: Antenna Alignment Procedure
ANTENNA ALIGNMENT PROCEDURE Satellite Alignment Alignment with the satellite is obtained by setting polarization, elevation, and azimuth. Charts are provided on page 11, 12 and 13 to determine the values for your earth station antenna site. “∆L” is the difference between the earth station antenna site longitude and the satellite longitude. - Page 11 Azimuth Use Azimuth Chart on page 13 and determine your azimuth setting. Values in chart must be adjusted for magnetic deviation for your location for correct Top Plate compass reading. Locking Equally tighten the six azimuth Bolt locking bolts until snug. This will (4 Places) allow the reflector to rotate with slight resistance.
