Is skew/rotation setting necessary on single LNB?

    My installer said that setting the skew on a SD single LNB dish was not necessary.
    when I check my location on geosat finder it indicates a rotation of 15.47 degrees.

    I know my numbers look pretty good, but i would like to minimize rain fade as much as possible and was wondering if this would help assuming, that it can be adjusted.

    Would this help tweak my signals? See signal strength attached.

    Your signals should be better than that. I would look at line of sight issues first, cabling/connections second (rg59 or rg6). Are there trees where the dish is pointing?
    Maybe the dish isn't secure enough with the recent winds in the northeast (im in NH).

    Rotating the LNB has no effect on circularly polarized signals. You can reduce your susceptibility to rain fade by installinmg a bigger reflector.

    Your signal levels look pretty good to me, but receiver signal meters are primitive and vary from model to model.

    Those signal readings are fine. There is no skew adjustment required when you're just trying to hit one satellite (single LNB dish).

    There is no tilt setting on the old single LNB 18" dish, only elevation and azimuth. The 3 LNB dishes and now the 5 LNBs have a tilt adjustment.

    Now it looks like you have a newer receiver, are you sure you don't have the 5 LNB Slimline dish? It may appear to have only one LNB from afar since it's a single housing for all the LNBs.

    Money could help this one!

    In HS I was in a group of guys that had to drive to Baltimore, MD to see the bare nekid women in the burlesque strip joints. We all bought tickets outside and as we walked through the lobby a guy came from a door and said, "Hey men, wanna see it all up close and personal?...gimmie another buck each and follow me."
    Of course we did. Then we entered the front of the theater through a side hall; same show.......cool!......but one dollar extra. We all learned different lessons.

    So call the installer back and tell him the skew on the 18" dish is incorrectly adjusted.......you want 15 degrees off center or else! Offer money.

    You're joking, right? There is no skew adjustment for the 18" single LNB dish.

    Left all that behind to join the fast moving herd in telecommunications.
    Are they not the tasks of a a home service provider?
