    Hi Texas brit.
    What you call tilt I call twist or skew. Tilt for me is elevation.
    I will remember about the height in the sky of the sats depending on where you live. Thanks

    You did good. The ones that are low are spot beams that don't apply to your location. All of the "s" satellite beams are spot beams, and there is only one that has to be max for your location.

    Yea ... its all about semantics;

    For me personally, its "azimuth," "elevation," "tilt" for movement around the dish's perpendicular axis, and the term "skew" is reserved for the adjustment of linear LNBs to parallel the received signal's plane of polarization. :)

    Me too. "Skew" isn't really applicable to DirecTV because it uses circular polarization. With most FTA signals, and services such as Shaw Direct in Canada, which use linear polarization, you need to rotate the LNB itself as you say to be parallel to the polarization of the signal.

    LOL. I don't even know what all that means. Too technical for me.

    "Skew" is a term used to line up the LNB [when linear polarization is used] to the North pole of the SAT, and not the north pole from the dish.
    "Tilt" as used with DirecTV, is to line up the dish LNBs to the same arc of the SATs. All but one DirecTV SAT uses circular polarization, so there isn't any need for pointing anything north.
