I have aligned a DTV dish for a guy and it seems to work fine. I just can't get past one little thing. He had a 3LNB setup that was set for 40 degrees elevation and 70 degrees skew (of which, is what it is suppose to be in this area). I put up the new 5LNB dish and able to get it dialed in fine but the dish shows it being lined up 22 degrees elevation. When I hold the old dish next to the new one, it seems to be the same. When I dial in the new dish at the supposedly correct 40 degrees, it points way high into the sky. Are the new slimline dishes different in the fact the the degrees scale needs to be multiplied by 2 or something. Thanks, in advance for any help on this.
