3. Select the angle of elevation for your installation location from the AZ/EL table (see
section 6). For example, in Daun the angle of elevation for the ASTRA 19.2° East
satellite is 31.29°.
Because your external unit has an offset dish, the angle of elevation to be set is not
the one you read from the table, but is rather an adjusted angle for the dish. This is
calculated as follows:
Angle of elevation minus offset angle = angle to be set.
The offset angle for the DigiDish 33 and the DigiDish 45 is 30°.
Thus, the angle at which the DigiDish 33 and 45 need to be set in Daun is as
follows:
4. Loosen the screws (D) on the swivel mount so that the external unit can be moved
up and down. Place a straight edge over the dish as shown in Figure 4. Set the
angle you calculated using an angle gauge.

5. Now loosen screws (C) and (B) on the swivel mount and rotate the dish slowly in
the East-West direction (azimuth angle) until you obtain a television picture from the
receiver.
6. At this point, the dish still requires fine adjustment. When doing this, it is a good
idea to call up the transponder information (see the operating manual for the digital
receiver).
7. Then carefully adjust the azimuth (East/West) and elevation angles to obtain the
maximum amplitude as indicated on the the level and quality display.
8. Once this is done, tighten all of the screws and make sure that reception does not
become worse while you are doing so.
The installation of the dish is now complete and the dish is properly pointed at the
desired satellite.
31,29° - 30° = 1,29°
