Prerequisites for
antenna pointing
Outdoor pointing
interface
One person can point the antenna if an outdoor pointing interface
(OPI) is used. Otherwise, pointing is usually a two-person task. If
an OPI is not used, one person aims and adjusts the antenna while
the other watches the signal strength display on a computer and
relays the readings to the person at the antenna. A portable
telephone or walkie-talkie is helpful for this.
Prior to antenna pointing, you use the installation software to
enter parameters such as longitude, latitude, and polarization
angle. Or you can enter the local ZIP code and let the software
calculate these values.
The following are required for antenna pointing:
• The antenna must be installed.
• The IDU must be installed.
• The transmit and receive cables must be connected to the
IDU and ODU.
• The OPI, if used, must be installed. (See Installing the OPI
on page 58.)
• The ODU and IDU must be grounded.
• You must have access to the installation software through the
IDU.
The OPI (Hughes P/N 1031393-0002), shown in Figure 45, is an
optional tool that displays signal strength values.
