FAQ 62-2002-en

In a satellite TV installation, most of the satellite channels are not received correctly except those that I know are received with a high power level.

Respuesta: 

The LNBs have to be installed with a certain skew to obtain the correct polarity discrimination.

Usually, when a dish is orientated towards a satellite positioned to the east, its cable comes out from the left-hand side (when looking at the dish from the front)

When the dish is oriented towards a satellite positioned to the west, its cable comes out from the right-hand side.

The internal sensors of the new LNB, ref. 7475, are inverted.

Because of this, to receive satellites positioned to the east, the cable comes out slightly sloped to the right.

As well as this, it is always necessary to carry out a polarity discrimination adjustment, using a Field Strength Meter.
