Choosing The Site for Dish Installation
The first thing you need to
do is choose the installation site. The area must have a clear "line of
sight" to the satellite. This means there can be no obstruction between
the dish and the satellite. This includes building, tree branches,
mountain, etc. In order to receive a good signal, select an outdoor site
with a clear, unobstructed view of the South, Southeast, or Southwest.
If you install the dish in the winter, leaves that are normally on the
branches may not be present. A problem with reception may occur when the
leaves grow back in the spring and summer.

- Insert the Stand Pipe between the two
ears of the Mount Bracket as in Figure 1.
- Ensure that both the pivot bolt and
the adjustment bolt are in place as in Figure 2.
- The top of the Stand Pipe must be
mounted vertically, perpendicular to the ground, otherwise it will
complicate pointing the dish at the satellite. We suggest using a
contractor's level and placing it on top of pipe the pipe as in
Figure 3.

| Dish Pointing Basic
To receive broadcast signals for Telstar 5
or any satellite, your dish must be positioned correctly. The exact
direction that your antenna will have to be pointed is dependent upon
your location. The elevation angle is the angle relative
to the horizon, that the antenna must be raised in order to be able to
receive signals from a particular satellite. The azimuth
compass bearing is the compass bearing, left to right, that the antenna
must be pointed toward in order to receive the satellite signal. Those
two angles will help you determine if the location you have selected for
placement of your antenna will permit unimpeded satellite reception. To
calculate the elevation and the azimuth, you need to know the satellite
degree and your Zipcode. For example: Telstar is located at 97° W,
SatMex is at 116.8° W, and Galaxy 11 is at 91.0° W. If you are not
familiar with the orientation of the location where you would like to
place the antenna, a directional compass will be very helpful.
- Hold the compass horizontally in your
hand in front of you.
- Ensure that you are at an adequate
distance away from any metal object that may give you a false compass
indication. As you hold the compass, allow the compass needle to stop
moving. Once it has stabilized, the arrow or red end of the compass
needle should point toward the North.
- Gently rotate the compass such that
the 0-degree mark on the compass scale sits under the arrow, or red
end of the needle, pointing toward the North
.
- Since 0 degrees on the compass denotes
North you can now locate the compass azimuth bearing on the compass
scale. You will probably note that the direction of the satellite, as
indicated on the angle calculation or data sheet, is somewhat towards
the South. That direction is the physical direction that the dish will
have to be pointed.
- Once you have oriented yourself in
that direction, consider the elevation angle. Now, make a judgment
based on the elevation angle of where you live. Keep in mind that 45
degrees is halfway between 0 degrees and the horizon while 90 degrees
is straight up. If while looking in that direction, given both the
compass azimuth and elevation for your location, you do not see any
obstacles, that location should be adequate for the placement and
installation of your dish-antenna.

Dish Aiming Procedure
- With the dish facing South and an
unobstructed view of the sky, place the provided compass on the ground
10' to 20' behind the dish to avoid magnetic interference. Turn the
compass until the compass needle aligns exactly with magnetic North
(or make sure the color needle points north at 0 degrees). Use a
straight object such as a stick or rod between the compass and the
dish to match the Azimuth angle of your location. Move the whole dish
to face the same direction as the stick or rod.
- Set your basic elevation angle. Refer
to the elevation scale located on the elevation plate at the back of
your dish. To set the correct elevation angle, loosen the bolts that
connects the elevation plate to the triangle base just enough so that
the reflector can move up or down without binding. Carefully set the
elevation to the angle value of your area.

| Dish Alignment & LNBF
Mount
Before the
actual dish alignment can be done, it is necessary to connect a coax
cable between the LNBF, attached to the dish and your receiver. Both
connections use the standard coaxial F-connector. Now your dish will be
in position to lock in on the satellite signal. You will need to have
your receiver connected to your television.
It is recommended that you place your
satellite receiver and television set close to the dish during the dish
alignment procedure. If that is not possible due to where the dish is
located, a second person may be helpful to relay information seen on the
screen of the TV when the dish is being aligned. Do not turn the power
on until all the cable connections have been made. There are two options
when connecting the receiver to your television or monitor. The receiver
has both audio/video outputs as well as a regular coax output on either
channel 3 or 4. Attach the appropriate cables according to the system
you have. If you use the standard coax, channel 3 or 4 output, ensure
that you select the channel, 3 or 4, that is not used in your area for
local off-air broadcast television. Your television would have to be set
to the channel you selected, 3 or 4, in order for you to receive the
programming. If the audio/video outputs are used, your television
typically would need to be switched to the "video" input mode.
Now turn on your receiver and television.
Use the on screen menu to locate the signal strength meter on your
television. If you are using the Coship receiver the signal meter are
located both in front of the receiver as well as on screen.
Ask a helper to watch the signal strength
screen for indications you are receiving the signal. Stand behind the
dish, and holding its outer edges, slowly turn it a little to the left
or right about 3 or 4 mm at a time to adjust the azimuth. Pause 4 or 5
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 then adjust the elevation for maximum signal quality.
Note:
The Signal Strength reading does not need to be "100." Lock in on the
highest possible signal. |
