SITE SELECTION
The main objective in conducting a site survey utilizing a compass and inclinometer is to choose a mounting location that
will give you the greatest amount of swing for azimuth and elevation for present as well as future use. A thorough
preinstallation site survey is strongly recommended because it can alert you to any "look angle", soil, wind or other
problems.
The first and most important consideration when choosing a prospective antenna site is whether or not the area can
provide an acceptable "look angle" to the satellite. Your antenna site must be selected in advance so that you will be
able to receive the strongest signal available. Also consider obstructions that may occur in the future such as the
growth of trees.
Prior to beginning the site survey, the site location and satellite look angles must be determined.
Determine your site latitude and longitude and enter the values here:
LATITUDE
Based on your site location and the satellite to be used, determine the correct azimuth, elevation, and skew settings for
your installation. Using the charts (beginning on Page 11), obtain these values and enter them here for easy reference.

AZIMUTH
It is important to conduct an on-site survey with a portable antenna or with a compass and inclinometer to avoid
interference, obstructions, etc. When selecting "look angle," (Elevation/Azimuth) be sure to observe and take
readings approximately 25 degrees to the left and right, above and below your selected "look angle".
Once you have chosen a site, select a location and determine the type of installation mount to be used. The satellite
antenna can be installed on a ground pole, wall/roof mount, or non-penetrating roof mount with 60 mm (2-3/8") outside
diameter mast. The chosen mount type should be assembled and in place before installing the antenna. Refer to instructions
packed with mount for its proper installation. The mast pipe must be vertical and plumb to insure ease of alignment.
Before any digging or trenching for Interfacility Link (IFL) cables is done, information regarding the possibility of
underground telephone lines, power lines, storm drains, etc., in the excavation area should be obtained from the
appropriate agency.
As with any other type of construction, a local building permit may be required before installing an antenna. It is the
property owner's responsibility to obtain any and all permits.
