[QUOTE="nopfusch, post: 497873, member: 195487"] Robbo71 I understand that, when you have a normal LNB. Here the whole LNB is turned and remains in that position, as the dish remains always at the same position as well. The feedhorn is fixed to the dish and moves (turns) as the dish moves and the skew setting is then obviously different for the polarities at any other azimuth, as we having here a [U]mechanical [/U]adjustment (skew motor), versus an electrical switching from e.g. 13V to 18 V (H / V), where the LNB remains in the same mechanical (e.g. 52 degree) position. There MUST be an adjustment other than zero and 90 degrees. The 52 degrees is correct when a normal LNB is used. So I should get 52-90 = -38 degrees for the other polarity, but no chance. Where is my mistake? The other statements were rather a comment and for newcomers rather discouraging information on these web sites, to use a 9m dish when there is a 3m dish more than adequate. Or the info from the satellite's owner are wrong. [/QUOTE]
