    You can always try the old crisscross string method

    It is important to have the scaler Ring in the middle of the dish at 4 points like where the arms are but what i do not understand is the Scaler ring, the hole is bigger than the LNB itself and when
    you tightened it it goes to one side about 2 to 3 mm > Now I have spent 1 hour trying to get my scaler ring in the middle no more that 0.1 MM out and yet that screw pushes the LNB 2 to 3 one
    way and not in the middle so what can you do about this

    Thanks for that. If they want you to keep the scaler ring in BULL EYE middle Why not keep the LNB that way too.
