First select the satellite you want to find, using the pull-down menu in small box at the lower left.
Put your mouse at your site location and drag the map to the middle..
The map display will move so that the selected point is in the centre. The latitude and longitude of the map centre is then displayed under the map, together with your satellite dish mount pointing azimuth, elevation and polarisation angles. To refine accuracy, click on the plus (+) sign in the zoom boxes at the upper left of the map. The scale will change so that you can home in accurately on your location. Repeat. Choose the "Satellite" or "Street" map version to see the satellite photo image of the ground and your city or town streets.
Set the dish elevation angle first. This is the up and down angle. There may be an elevation scale on the back. Set the polarisation or skew angle also. This involves starting with the LNB upright. Then adjust it by rotating the LNB by the calculated amount. There may be a polarisation rotation scale on the feed throat. Use the tic marks to determine the amount of angle but ignore the sign +/- if it is the wrong way round Facing the satellite, clockwise is positive. You may have to turn the LNB almost 80 deg or so, in some cases. For the side-to-side azimuth bearing use a compass or just think where the sun is and the time of day and boldly swing the dish sideways. West is 270, North is 360 or 0 deg and East is 90 degrees. You should find the satellite on the first swing, then spend half an hour peaking up. Peaking up the aiming is really important for long term service quality and minimum outage time during rain fades.
The two angles you need are provided on this page: Dish pointing USA. Only your latitude matters. There are two angles: Set the main polar mount axis angle and the small downward tilt of the dish, and with the motor central, align the dish the whole assembly towards the due south satellite. Motor rotation angles to the east are positive, to the west negative.
