Reception in remote areas
This chapter describes how to optimise the reception in areas near the edge
of a satellite footprint, by readjusting the LNB. For this, the LNB has to be
unscrewed and be turned to a certain angle. This optimizing is only necessary
in remote areas. This operation is only recommended for people with compe-
tence.

State-of-the art digital technology can considerably enlarge the area in which a
satellite can be received.
Most satellites broadcasting channels of interest to Central European viewers are
aimed at Central Europe. In locations outside this area, the antenna has a lateral
„view" on the satellite. This effect is known as the „skew angle" or „polarization
angle" and occurs particularly in southern regions such as Portugal, Spain, Morocco,
Greece, Turkey, and most extremely on the Canary Islands.
This effect is mostly compensated by the receiver's electronics, but sometimes re-
quires some manual fi ne-tuning by pivoting the LNB (reception head) or the com-
plete fl at-panel antenna by some degrees.
The following defi nitions apply to the following tables and angles:
To determine the sense of rotation, the viewer looks towards the satellite from the
perspective of the antenna. Accordingly, the viewer is located behind the antenna or
at its side. Depending on the antenna model, either the LNB in front of the anten-
na dish (Oyster®), the LNB within the antenna (Cosmo®) or the complete antenna
(Caro®) must be turned.
Rotations in CLOCKWISE direction are negative (–).
Rotations in COUNTERCLOCKWISE direction are positive (+).
A rotation in „+" direction hence means that the BOTTOM of the LNB or
antenna is turned to the RIGHT.
A rotation in „–" direction hence means that the BOTTOM of the LNB or
antenna is turned to the LEFT.
