Ausrichten der Satelliten-Empfangsanlage (Fig. 6)
If the feed system is only to be exchanged,
the antenna does not have to be aligned.
1. Align according to enclosed azimuth/elevation table.
2. Tune to wanted satellite (see enclosed azimuth/eleva-
tions table) by turning the antenna around the azimuth
axle until max. signal level is obtained (if a Kathrein
signal meter MSK... is used), or until best signal
strength/quality is reached (see Fig. 7 and „Level opti-
mization“).
3. Adjust elevation until max. signal level or best signal
strength/quality are obtained.
4. Check azimuth adjustment and correct if necessary.
Firmly fix all bolts to advised torque moment M
A
(see
mounting instructions for parabolic antenna).
5. Continue as described in section “Cable connection”.

Level optimization
As the antenna lobe (Fig. 7) in the maximum range is only
slightly curved, an excellent signal strength/quality can
be expected when it is aligned to this range. However, it
may also be that the antenna at the left or right is “only
just” aligned to this excellent reception range. As soon
as the antenna stanchion experiences any vibration the
supposed excellent signal strength/quality can drop off
at the steep edge of the lobe. To avoid this, the recep-
tion position should be set to the middle of the maximum
level.
Proceed as follows when conducting the setting-up
process using a Kathrein test receiver (MSK...):
1. Mark the centre of the mast clamp.
2. Turn the antenna to the left until the level drops by, e.
g. 8 dB. Transfer the mast clamp marking to the mast.
3. Turn antenna to the right until the level drops by 8 dB.
Transfer the mast clamp marking to the mast.
4. Position the mast clamp marking in the exact centre
of the mast markings. This will ensure that an ideal
reception situation is given.
5. Proceed in a similar manner to optimise the elevation.
