Reception in remote areas
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 requires some manual fine-tuning by pivoting the LNB
(reception head) by some degrees.

As seen from the LNB looking into the antenna dish, positive degree
numbers require a CLOCKWISE and negative degree numbers a
COUNTER-CLOCKWISE pivoting of the LNB. Adjustments of less
than -15° are usually not required as long as reception is undisturbed.
