8.1 FOOTPRINTS: SATELLITE
TRANSMISSION AREAS
Satellite television is one of the few means which
allow receiving information in any part of the world
within the coverage area of the satellite you wish to
receive.
The signal transmitted by the satellite generally has
a wide coverage area, as shown in the purely indic-
ative footprints below, and thus guarantees vision
of the same TV programmes in various areas.
However, it is important to remember that ground
obstacles are the main causes of satellite antenna
malfunction.
Ground obstacles include all bodies which could be
located between satellite and antenna, such as
trees, cranes, buildings, overpasses, bridges, gal-
leries, etc.

The signal transmitted by the satellite is also
affected by weather conditions (storm clouds or ice
clouds).
The footprints show the satellite coverage areas on
the Earth for satellite antennas Discovery and
Explorer under favourable weather conditions.
S
In case of bad weather, signals will be weaker;
therefore, the image quality could be reduced, up
to completely fading away. It is also very important
to make sure, upon purchase, that the dimensions
of the satellite antenna are the most appropriate
ones to receive the signal in the areas where you
spend your holiday. Footprints are indicative and
referred to the satellite with the strongest E.I.R.P.
(Equivalent Isotropic Radiated Power).
