PRECISE SITE SURVEY
Based on your general site survey, you probably already know where you want
to mount your dish, but it's a good idea to follow the pro c e d u res outlined in this
section in order to make sure that your site selection is a good one.
1. Go outside to your install site and hold a compass flat in the palm of your hand.
Hold your hand still until the needle stops moving (the dark or colored half of
the compass needle always points North).
2. Rotate the compass so that the "N" (for North) is directly under the dark part
of the compass needle. Your compass is now aligned with North. The marks
around the outside edge of the compass represent the azimuth degrees you
will point your antenna to.
3. Locate the tick mark on the compass edge that corresponds to the azimuth
number you wrote down. This is the direction of your azimuth setting (the
d i rection the dish will need to be pointed to receive signals from the satellites).
Pick a landmark or lay down a stick in that direction for reference from the
mounting location.
4. Raise your arm to approximately the e l e v a t i o n angle re c o rded earlier to make
sure that there are no obstructions in the signal path. Use an inclinometer or
protractor to more accurately estimate the elevation angle.
5. Repeat this survey in several places on your property if necessary until you
find the best mounting location.
F rom this rough sighting, allow plenty of clearance for the final alignment.
Remember trees grow up and out, which may possibly block the signal in
the future.

Ti p
T ry to keep the compass away
f rom any metal objects. Metal
objects can cause inaccurate
compass readings.
WARNING
Do NOT install the dish near
power lines, electric lights or
power circuits. Contact with
power lines, lights or power
c i rcuits may be fatal. It is
s t rongly recommended that the
dish be located more than 20
feet from overhead power lines.
