Pointing the antenna by using
the DAPT3
This chapter explains the antenna pointing process using the LUI and the DAPT3.
DAPT3 has an additional feature of measuring power on the IFL line which allows
the modem to perform cable calibration for dual IFL linear HT1300 terminals.
Prerequisites
Before pointing the antenna, you must perform the following steps:
1.
Assemble and install the antenna at the selected location following the
procedures in the installation guide for the specific antenna model.
2.
Run the intra-facility link (IFL) cable between the SAT connector on the
satellite modem and the IFL connector on the antenna radio.
Entering installation parameters
This section explains how to obtain the proper azimuth and elevation coordinates at
the customer location to point to the satellite using the LUI.
1.
Use your GPS receiver to determine the latitude and longitude of the
installation site and record them.
Note:
Hughes IDU software does not use negative values to denote south
or west. You must specify the hemisphere of the coordinates.
Latitude: ________Degrees _____Minutes _____Fractional minutes (N/S)
Longitude: ______Degrees _____Minutes _____Fractional minutes (E/W)
2.
Using an Ethernet cable, connect your laptop to the satellite modem LAN
port, as shown in
on page 14.
