Chapter 7 • Pointing the antenna

1037312-0001 Revision A

Personnel requirements

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.

Pointing parameters

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.

Prerequisites for

antenna pointing

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.
