3.10 Reception in remote areas
This section describes how to fi ne-tune the LNB to optimise reception in the
fringe of a TV satellite‘s footprint. This requires loosening the antenna bolts
and turning the antenna to a different angle. Such optimisation is only re-
quired in the fringe areas of a satellite‘s footprint. It should be performed by
expert users only.
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 „sideways
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.
The 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 entire
at-panel antenna by some degrees.
The following defi nitions apply to the tables and angles below: To determine the
sense of rotation, the viewer looks towards the satellite from the perspective of
the antenna. Accordingly, the viewer must be located behind the antenna or at its
side. Depending on the antenna model, either the LNB in front of the antenna dish
(Oyster®), the LNB inside the antenna (Cosmo®) or the entire antenna (CARO®) must
be turned.
Rotations in CLOCKWISE direction are negative (–).
Rotations in COUNTERCLOCKWISE direction are positive (+).
Accordingly, a rotation in „+“ direction means that the BOTTOM of the LNB or
antenna is turned to the RIGHT.
A rotation in „–“ direction means that the BOTTOM of the LNB or antenna is
turned to the LEFT.
