Aligning The Antenna - Kathrein CAS 120 Mode D'emploi

5. Setting polarisation angle
One feed system (mono feed)
Adjust the polarisation angle according to the tables
(see feed system) on the feed system depending on
your mounting site and the position of the received
satellites.
The swivelling support H remains in the zero position.
Mounting several feed systems (multifeed)
For multifeed reception, the swivelling support H must
be moved to the angel V according to the supplied
azimuth/elevation table for multifeed reception. In this
case, the polarisation angle on the feed system is not
adjusted according to this table, but rather to the cal-
culated correction angle :
PW = PW - V

7. Aligning the antenna

With regard to the direction (Azimuth) and the inclination
(Elevation), the antenna must be accurately aligned to
the satellite. For multifeed reception, it is necessary to
align the antenna to the satellite with the weaker signal
level.
a) Setting the inclination (Elevation)
When setting the elevation of the antenna, loosen the
6 screws A on the elevation scale.
When you lightly tilt the antenna by hand, you can turn
the nut B (for fine adjustment) faster for rough adjust-
ment or pre-adjustment of the elevation angle.
Now set the elevation. You find the correct angle of
the elevation for your mounting site in the mounting
instructions supplied with the feed system. Set this
angle on the scale (10° to 50°). Here, the respective
scale line on the support must be aligned with the
edge C of the reflector support sheet.
Lightly screw on the screws A.
