Terminal Commissioning And Antenna Alignment

14. ANTENNA ALIGNMENT METHOD

14.3 POINTING OVERVIEW

Antenna pointing is a critical part of the antenna installation process. If the antenna is not properly pointed

toward the satellite, the IDU cannot communicate with the satellite to full capacity, and performance will

be degraded. The Hughes Net system uses a narrow Ka-band beam that can be sensitive to pointing errors, so

proper and accurate antenna pointing is essential.

To point the antenna you adjust azimuth and elevation while you use the Horizon HD-S2A or AMA to

measure signal strength in a defined series of steps.
