Satellite Dish
A satellite dish is an antenna to receive the satellite
signals that are reflected onto the feedhorns mounted
to the dish. The dish size required for AsiaSat reception
in general depends on the following:
| 1. |
Geographical location
within AsiaSat's footprints |
| 2. |
Services to be received:
C-band or Ku-band, analogue or digital, SCPC (single
channel per carrier) or MCPC (multiple channels
per carrier) |

Ku-band Australasia Beam Digital MCPC Channel
The dish size for SMATV system depends on the satellite's
signal strength at the reception location and the number
of receivers connected to the system. A larger dish may
be required in order to compensate for signal distribution
losses.
| How to point your
dish? |
 |
The dish should
have a clear view to the satellites you want
to point to |
|
Determine the azimuth
and elevation angles (also termed "look
angles")
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. |
