Page 5: Antenna Alignment Procedure
ANTENNA ALIGNMENT PROCEDURE Satellite Alignment Alignment with the satellite is obtained by setting polarization, elevation, and azimuth. Charts are provided in this manual 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. Use “∆L”... -
