Hughes AN6-098P Manuale Utente

 

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 

• 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.
