Dish Antenna Installation
Mounting the Dish
1. Using the azimuth and elevation angles, find a location for the satellite dish
which can be pointed towards the satellites located at these angles. With a
compass, find the required azimuth angle. Then, use the elevation angle to find
out how high the satellites are in the sky from your location.
Make sure nothing blocks the line of sight between the dish and the satellites.
2. Mount the mast to a solid surface so that the dish antenna cannot move or be
bumped out of adjustment. Keep in mind that physical and environmental
conditions can block your satellite dish’s ability to receive a clear satellite
signal. The conditions to be aware of are: Eaves and overhangs on your building
or house, wind, plant growth, and deterioration of the mounting surface. Never
mount to a tree or a public utility pole.
3. Align the top part of the mast so that it is absolutely vertical, as shown below. If
the top part of the mast is off vertical by only a few degrees, it will be difficult or
maybe even impossible for you to find the satellites. Take at least two readings
with a bubble level, on the upper mast, that are 90 degrees apart from one
another.
