To receive satellite broadcast signals,
your satellite dish needs to be positioned correctly. You can do
this yourself.
Determining the Elevation and Azimuth - The satellites
are "parked" approximately 22,300 miles above the equator. In
reality, the satellites travel from west to east, but to us on
Earth they appear stationary because they match the exact speed
of the Earth's rotation. (This is a geostationary orbit.) If you
stand up now, turn towards the southern hemisphere, and tilt
your head up to the heavens, you'll be looking in the general
direction of our satellite
To calculate the azimuth and elevation angle for your location,
you may click on this Azimuth/Elevation link. We implemented
this software on our website and the link will now always work.

Elevation Reading
Now that you have your azimuth and elevation coordinates, what
do you do with them?
First, survey the site to ensure an unobstructed view in the
direction of the satellite. To receive broadcast signals, your
satellite dish needs to be positioned correctly. Mount your
satellite dish so that the base fits flush with the mounting
surface (level if mounted on a flat beam or roof, or on an angle
to match the pitch of your roofline). When you have securely
mounted your satellite dish, adjust your dish so that the dish
mast is plumb, that is, exactly perpendicular to level - this is
best achieved using a carpenter's level. With your dish now
mounted and properly set, you are now ready to aim your dish
toward the satellites.
To set the dish to point up to the satellites, you'll first need
to set the elevation. Then you'll point the dish in the proper
left-to-right position, to set the azimuth. You'll need to refer
to the installation manual for your system for detailed
instructions, but here's the short course.
Setting the Elevation (UP), (DOWN)
You can set the proper elevation after the dish is securely
mounted. First, loosen the nuts securing the two elevation bolts
so that the dish easily moves up and down. Line up the elevation
indicator with the tick mark corresponding to your elevation
number. Then tighten the bolts. You may need to readjust the
elevation up or down slightly to get the best signal. See figure
on top.
Setting the Azimuth (LEFT), (RIGHT)
Loosen the azimuth nuts on the LNB arm enough that the dish can
be turned smoothly with little pressure. Set the azimuth by
moving the dish left and right. Point the dish in the general
direction of the satellite, in the southern hemisphere. By using
a compass you can better pinpoint the direction with your
azimuth number to correspond with the degrees on your compass.
See figure on top.
Acquiring the Signal
Now your dish will be in position to lock in on the satellite
signal. You'll need to 1) have your digital receiver connected
to your television, with both turned on, and 2) have your
antenna LNB to receiver cables connected, and 3) be viewing your
Setup Antenna/Signal Strength display from your digital
receiver's on-screen menu to measure the signal strength
accurately. To view the signal strength and quality of Star
Track Receiver press Menu and TP Configuration
Ask a helper to watch the Signal Strength screen for
indications you are receiving the signal, the upper meter is the
signal strength, the lower meter is the signal quality. Please
note that you will receive the signal ONLY when there is a
signal on the lower meter (signal quality). Stand behind the
dish, and holding its outer edges, slowly turn it a little to
the right to adjust the azimuth. Pause a few seconds, giving the
receiver enough time to lock in on the satellite signal.
Continue turning the dish in this way until you have acquired
the signal or until you have rotated the dish approximately 15
degrees from the starting point.
If you haven't detected a signal yet, return to the starting
point and move the dish to the left again. If you don't acquire
the signal after rotating the dish approximately 15 degrees to
either side of the calculated azimuth angle, loosen the
elevation bolts and tilt the dish upward so the elevation
indicator moves halfway from the current tick mark to the next
mark. Then tighten the elevation bolts.
If necessary, continue changing the elevation in half-tick-mark
increments until you receive the signal. After tilting the dish
upwards three tick marks beyond the original tick mark, return
it to the original tick mark and then tilt it down a half tick
mark. Keep repeating this until you receive the signal.
If the Signal still eludes you, check:
Check to make sure that the mount is 100% level. The portion
that the dish mounts on must be straight up to the sky level.
Otherwise you will not be able to find the signal
That nothing--a tree, for example--obstructs the signal that the
cables are connected properly to the receiver.
That you have the correct azimuth and elevation coordinates
Fine Tuning
Now that you have received the satellite signal, it is important
to fine tune the dish pointing to make sure you have the maximum
possible signal strength. Maximizing the signal is important, in
that, it reduces "rain fade" during inclement weather. Loosen
the elevation bolts, then gently continue turning the dish a
little in the same direction you were turning it when you began
to receive the satellite signal. Pause for a few seconds each
time after moving the dish. Turn the dish in this way until the
signal quality strength reaches its highest reading and then
begins to fall. Then slowly turn the dish the opposite way until
you again receive the highest reading on the Signal Strength
screen. Important: The Signal Strength reading does not need to
be "100." Lock in on the highest possible signal. Tighten the
azimuth bolts.
Loosen the elevation bolts. Slowly tilt the dish up and down to
improve the Signal Strength reading. When you are satisfied that
you have the strongest signal, tighten the elevation bolts.
