Chapter 5 • Pointing the antenna
 
1035567-0001  Revision A
39
By obtaining the strongest possible signal you ensure that the 
terminal can use all the system’s capacity.
Personnel requirements
One person can point the antenna if an OPI is used. Otherwise, 
pointing is usually a two-person task. One person aims and 
adjusts the antenna while the other watches the signal strength 
display on the 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.

The OPI, shown in Figure 34, is an optional tool that eliminates 
the need for a laptop computer on the roof. It is a portable 
repeater that displays the same values as are shown on the 
computer running the installation software.
