Chapter 2
Selecting an Antenna Location
This chapter contains instructions for selecting a location to install
the satellite antenna.
The sections covered in this chapter are:
□ Locating the Satellite
□ Choosing an Installation Site
Before you can select a location to install the antenna, you need to
find the direction and elevation'of the satellite relative to your
house. After you know where the satellite is located, you can find
a suitable location to install the antenna. Use the following
instructions to identify the directional coordinates and locate the
satellite.
Find the satellite direction with the
azimuth:
The azimuth is a compass heading used to determine the direction
of the satellite relative to your house. Once you know where the
satellite is located you can choose an installation site that has an
unobstructed view of the satellite.
1
Take a compass outdoors. Hold it level to allow the needle to
rotate freely.
2
Rotate the compass until the dial aligns with the magnetic
needle which is pointing North.
3
The compass dial has numbers ranging from 0° to 360°. Find
the azimuth coordinate you recorded from the map on the
compass dial.
Note
‘ • The arrows on the compass in this illustration indicates the azimuth
of major US cities.
Use the map to estimate the directional
coordinates:
Use the map below to estimate the directional coordinates of the
DSS satellite. You may also obtain the coordinates by using the
on-screen zip code or latitude/longitude features described on
pages 16 and 17.
Notes
• At this stage it is not necessary to find the exact location of the
satellite, A rough estimate is sufficient.
• The satellite is located due south of Texas over the equator.
• The azimuth is a compass heading.

-Use the azimuth and elevation markings on the top and side of
the map to. estimate the directional coordinates of the satellite.
(For example, the directional coordinates for Los Angeles are:
Azimuth: 135° and Elevation: 46°.)
