Instructions for
people in Europe pointing Ka or Ku band antennas at Tooway satellite service. Choose the satellite you want to see using the pull down menus at box at the lower left. Hotbird 6 (Ka band) is at 13 deg east orbit position. Eurobird 3 (Ku band) is at 33 deg east orbit position. In the upper, dynamic map, put your mouse cursor to your location and
then double click or simply drag the map. The map image
will move so that the chosen point is in the centre. The latitude and
longitude of the dot at the centre of the map is then displayed below the
map, together with your satellite dish pointing angles: azimuth, elevation
and polarisation or skew angle. To improve accuracy, click on the plus sign
Dish pointing 1. Set the polarisation or skew first. In the case of the blue Ka Band antenna, note the large circular skew scale behind the dish. When the subreflector and TRIA support arm is at the bottom the skew scale reads 90 deg. The applicable blue dish skew angle is shown on the left. From the initial starting position you need to rotate the dish either clockwise or anticlockwise depending on location (east or west of the satellite orbit longitude (e.g. 13 deg east). The amount of polarisation adjustment necessary is also shown. Positive (+) adjustments are clockwise, with you standing behind the dish and facing forwards to the satellite in the sky. The polarisation of a Ku band dish may be applied either by turning the entire dish (e.g. Blue Raven dish or 1.2m Prodelin model) or by rotating the LNB/BUC assembly in it yoke (older designs). 2. Set the beam elevation angle (up/down) using the scale. You may find that it helps to set the elevation a couple of degrees higher than calculated to allow for sagging of the dish until everything is tight. 3. For the azimuth angle (sideways) use a magnetic compass and swing the dish boldly sideways to find the satellite on the first swing. Then spend half an hour peaking up. |

Peaking up is really important for long term service quality and minimum outage time during rain fades.
Setting the polarisation accurately avoids you causing interference to other peoples' service.
Safety Warning: The results of this page may be in error, The latitude and longitude are not intended for the blind navigation of aircraft, ship or other vehicle purposes. Dish pointing angles may be wrong. Magnetic azimuth bearings are approximate. Use is entirely at your own risk. Apply common sense and don't believe every number that comes out of a computer system. Take care with satellite dish pointing to not injure others by dropping tools or hurting yourself by falling down.
