Aligning the satellite reception system
Prerequisites
• The antenna must have an imaginary "line of sight" of the sat-
ellite (the visibility must not be obstructed by trees, buildings,
etc.) towards the south at an angle of 15° to 55° relative to the
horizon.
• The vehicle has to be positioned horizontally. The antenna
must be in the driving position.
Alignment procedure for the use of Sat jointed mast
1. Loosen the cross grip screw of the mast console and the cone
nut on the roof duct. Slide the antenna mast (HDM 140, HDM
143) from its lowered position at least 13 cm up, in order to
prevent it from colliding with the roof when it is swivelled.
2. Elevation adjustment
• Switch to the program position 1 on the receiver. This program position is assigned to the program ARD at ASTRA 19.2° East for Ka-
threin receivers and for most of the other receivers which are on the market in Germany.
• The antenna must be aligned to the south. Turn the crank handle of the jointed mast clockwise until the antenna has reached the
elevation position required for the reception site. The number of the necessary rotations can be gathered from the Azimuth/Elevati-
on table or the graph on page 12.
For the following steps you may need an assistant, if you yourself are unable whilst performing the setting to read the results of the
alignment work on an antenna meter or screen connected to the satellite receiver.
3. Setting the azimuth
After you have set the elevation angle correctly as described under "2. Setting the Elevation", turn the antenna mast slowly clock-
wise or anti-clockwise to the position that gives the best values for signal strength and quality.
4. After the alignment is finished, do not forget to screw on the cross grip screw on the mast console and the cone nut on the roof duct.
5. A graph for quick alignment of the antenna is found on page 12.
Tip:
Put the user guides in a clear plastic folder and fasten the folder to the door of a wardrobe ensuring they are at hand whenever
they are needed.
Maintenance
•
The BAS 66 Skew as well as the mounting accessories (HDM jointed masts) are maintenance-free.
Attention!
Before your start the journey, make sure that no parts of the antenna system are loose. Parts that are loose must be fastened.
•
Cleaning
Only clean the antenna with water and, if necessary, with standard cleaning agents for motor vehicles. Never use steam jet or
high pressure cleaners or solvent-containing cleaners such as acetone, nitro-paint thinners, benzine etc. These could damage the
antenna.
