-  Adjust  the  LNB  counter-polarisation.  This  operation  consists  in  adapting  precisely  the  LNB  angle  in  order  to  reach  a  maximum 
reception quality for a polarity, without interference with the opposite polarity. Observe the quality bargraph. Adjust the head until you 
obtain a maximum quality.
