Antenna pointing
overview
This document describes the HughesNet Ka-band antenna
pointing procedure. This document is written for professional
installers who have experience with installing and pointing
satellite antennas.
This pointing guide discusses the antenna pointing procedure
only. For an explanation of 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.
This guide applies to the following HughesNet System Ka-band
antennas: 0.74 m, 0.98 m, 1.2 m, and 1.8 m.
The antenna pointing procedure is a critical part of the
HughesNet antenna installation process. If the satellite modem
antenna is not properly pointed toward the satellite, it cannot
communicate with the satellite to its full capacity, resulting in a
degradation of system performance.
The basic requirement when pointing a HughesNet 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 HughesNet system uses a narrow Ka-band
beam which can be sensitive to pointing errors, and therefore it is
critical that the antenna is pointed properly and accurately. Be
sure to follow the procedures in this manual exactly as written to
achieve this goal.
The antenna pointing process is divided into three tasks: coarse
pointing, fine pointing, and pointing validation. Under normal
conditions and circumstances, a single professional installer can
perform this process alone (the one exception is when pointing
the 1.8m antenna, which requires two people to install, due to its
large reflector.)
