LNB SETTINGS IN DIFFERENT REGIONS:
The following settings are needless at Oyster SKEW units. This section describes how to fine-tune the LNB to
optimise reception in the fringe of a TV satellite’s footprint. This requires loosening the LNB or antenna bolts and
turning either component by a specific angle. This is only required in the fringe areas of a satellite’s footprint. It
should be performed by expert users only. 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 “polarisation 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 some manual fine-tuning is required by
pivoting the LNB (reception head) or the entire flat-panel antenna by some degrees.
