The
easiest way would be, of course, to call a satellite dish installer
and ask him to install your dish and point it to AsiaSat 4 satellite
(122.0 degrees E, frequency 4120, horizontal polarization, bitrate 27500,
vitebri rate 3/4, enter
here to see the full list of TV channels transmitted from AsiaSat
4)
But if you wish to install it on your own, then read on.
1. Assemble the antenna
2. Mount it firmly on your roof, so
that it is not blown away with the wind and alignment to the satellite
is not disturbed
3. Deternime your exact geographical
location, latitude and longitude, use a map to find this information
4. Click
here to enter latitude and longitide in the online calculator
and get the exact elevation and azimuth for your location
5. Now, having that data in hand,
you need to point your antenna to AsiaSat 4 satellite
How to do it?
Set the dish antenna vertically pointing to the true north. The
dish should have a clear view to the satellite you want to point
to (no trees, buildings).
The azimuth and elevation angles are the horizontal and vertical
angles respectively for the antenna to point to the satellite. The
azimuth is in clockwise direction from the true north. The elevation
is the angle for which the antenna moves upward from the horizon,
pointing to the satellite. Now, apply a little intellectual effort
and point it to the satellite.
6. Now set the LNB in the horizontal
polarization. What is horizontal polarization?
Polarization - Correction between
where the antenna is relative to the curvature of the Earth and
the satellite's signal beam. The satellite signal is either Horizontal
or Vertical polarized, but due to the longitude of the antenna location,
the antenna's feed horn must be rotated to correctly match the beam's
polarization.The following illustration will better show the relationship
between azimuth, elevation, and polarization.
Polarization

The port on the LNB where the coaxial cable is being
connected must be 300 to 320 degrees clockwise, that will be vertical
polarization.
If that was not really clear for you, you can find the vertical
polarization by installing your DVB card in the computer (go to
step 9 below) and gradually turning the LNB and watching increase/decrease
in signal strenth through the DVB card application software. You
need to find the strongest signal LNB pozition. (It is assumed here
that you have pointed the dish to the satellite correctly)
7. Prepare the coaxial cable and screw
the connector on the cable end. See how to do it below.

8. Plug the cable into the LNB and
take it to the DVB card in your computer (do not make the cable
too long, because the signal strength decreases as the length increases,
due to the increase of cable resistance).
9. Download
the manual which will help you install the DVB card and configure
the computer, having plugged in the cable into the DVB card (Warning
- do not plug in or unplug the cable with the computer turned on,
your DVB card can get damaged because of some electrical power present
in the cable).
