Determining the
Elevation and Azimuth:
|
Compass:
Rotate the Compass until the painted tip of its needle is on
the Zero
or (N) mark on compass face for proper orientation. The EAST
will be at
the 90 degrees, the SOUTH will be at 180 degrees and the
WEST at 270
Degrees. |
 |
 |
|
Azimuth (Magnetic):
Move the dish Left and Right until the LNB arm is pointing
to the
magnetic azimuth value for your location. |
 |
 |
|
Elevation:
Move the Dish up and down and set the elevation indicator on
the value
of the elevation value for your location. |
 |
 |
|
Elevation Indicator:
Be sure to locate the Elevation indicator ( or equivalent ,
depending on
your dish) . Use this indicator to set the correct elevation
of your
location. |

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 find out the azimuth and elevation angle
for your location: (City and State),
use the above
calculator on this page!

Elevation of your State or Province
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 roof
line). 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.
Setting the LNBF
Polarization Tilt (Skew):
The LNBF and/or its bracket (s) are
marked in degrees to indicate the polarization tilt or the
(SKEW). The
proper skew varies with location but within plus or minus 30
degrees in
the USA except for Hawaii where the skew is minus 65 degrees.
The 30 degrees equals 5 Minutes on the
minutes scale of a regular clock. The 30 degrees also equals One
Hour on the
hours scale of a regular clock. The feed cable at the bottom of
the LNBF is
usually used to indicate the 6 O'clock mark when it is vertical.
Generally the skew is zero if you are in
Huston, Texas. At the West States like California the skew
could be as
minus 30 degrees ( Clockwise rotation which equals to 7 O'Oclock
of the feed
cable when looking toward the Dish). In Maine the skew could be
up to plus
30 degrees ( Counter Clockwise rotation or 5 O'clock if looking
to the
Dish). Looking at the Satellite(reversing the looking direction)
the skew
for California will be 5 O'clock and for Maine it will be 7
O'clock.
During the final tune up phase, the LNBF
should be rotated in both directions to optimize the signals
and/or the quality
levels.
Acquiring the
Signal:
Depending on your kind of digital receiver you will be
able to see either the received signal level only or to see both
the signal
strength and the quality meter also.
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 (Satcruiser
receivers Telstar 5 for example) press Menu, Installation, TP
Configuration,
select Telstar 5 and frequency 12152 or frequency 11898.
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.
Polarity can play an important role in
whether you are able to receive the digital signal at all.
Digital signals are
not as forgiving as analog signals, it is either you receive it
or you do not.
For the SatCruiser Receiver only , If the signal meter
shows a high signal
(over 85% ), and you are still unable to receive the digital
signal, then
adjusting the SKEW will almost always help. For the Starcruiser
Receiver
adjusting the SKEW will maximize the signal level.
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.
