Antenna pointing overview

This document explains how to point JUPITER system antennas. This document is
written for professional installers who have experience with installing and pointing
satellite antennas.
This pointing guide discusses antenna pointing only. For antenna installation and
mechanical adjustments on the antenna, see the specific installation guide for the
antenna you are installing. A Ka-band radio assembly must be installed with the
antenna before pointing.
The antenna pointing procedure is a critical part of the JUPITER antenna installation
process. If the satellite antenna is not properly pointed toward the satellite, it
cannot communicate with the satellite to its full capacity, resulting in degraded
system performance.
The basic requirement when pointing a JUPITER antenna is to accurately aim the
antenna at the satellite to within 0.2 dB maximum loss of reception and 0.45 dB
maximum loss of transmission. The JUPITER system uses a narrow Ka-band beam
which can be sensitive to pointing errors; therefore, it is critical that the antenna is
pointed properly and accurately.
To accurately point the antenna, follow the procedures in this manual exactly
as they are written.
The antenna pointing process is divided into three tasks:
 Entering installation parameters
 Pointing
 Registration
Under normal conditions and circumstances, a professional installer can perform
this process alone.
