To determine the adjustment parameters of the Skew angle for the LNB, identify your position in the map of
Europe and choose the corresponding parameters in the LNB Skew Table on page 20.

Satellites transmit signals on two (horizontal and
vertical) polarisations which are orthogonal between
each other.
In order to optimise signal reception, the receiving
element Converter/LNB, which is mounted on the
parabolic antenna, must be positioned to be perfectly
aligned with the transmitted signals. When this does
not happen, because of a different geographical
position, the Converter/lNB must be rotated, “Skew
angle”, in order to optimise its alignment with the
signals it is receiving (fig. 15).
A typical example of this situation is the reception of
the following satellites: Astra 28,5E, Astra 19,2E or Hot
Bird 13E in countries like Portugal, Morocco, Turkey or
in Eastern European countries.
The Converter/LNB has been installed on the antenna
in a position that is suitable for allowing the correct
reception of the main satellites in most European
countries.
ATTENTION: The rotation of the LNB must not be
changed if the vehicle stays in the same geographic
area and you are receiving your signal from the same
satellite.
To access the LNB converter, remove the
protective plastic covers by unscrewing the three
parametric screws. Once the skew is adjusted, if the
vehicle stays in the same geographic area and is
receiving the same satellite signal, we recommend
that you screw that protective plastic covers back on.
