e) Feed system (LNB)
The feed system(s) and instructions for their installation are not
included in the scope of supply of the parabolic antenna.
For more detailed information on their correct installation please
refer to the manuals supplied with the respective feed system.
• You can use the
multi-feed adaptor plate
on the carrier arm to
mount one or two Kathrein Universal Feed Systems on to the
tiltable support on the carrier arm. The markings on the adaptor
plate are as follows:
-
3
the installation position for
one single
feed system,
-
2
and
4
the installation positions for
two
multi-feed feed systems
at
3°-4° satellite spacing,
-
1
and
5
the installation positions for
two
multi-feed feed systems
at
6° satellite spacing.
• Example for the installation positions for a multi-feed application
with
3°-4° satellite spacing:
Item 2 Item 4
ASTRA 19.2° East EUTELSAT 16° East
ASTRA 23.5° East ASTRA 19.2° East
EUTELSAT 16° East EUTELSAT 13° East
EUTELSAT 13° East EUTELSAT 10° East

Multi-feed
adaptor plate
Tip:
For multi-feed applications the antenna should be aligned
towards the satellite which is transmitting the weakest signal.
• Example for the installation positions for a multi-feed application
with
6° satellite spacing:
Item 1 Item 5
ASTRA 19.2° East EUTELSAT 13° East
EUTELSAT 16° East EUTELSAT 10° East
EUTELSAT 13° East EUTELSAT 7° East
Tip:
For multi-feed applications the antenna should be aligned
towards the satellite which is transmitting the weakest signal.
f) Polarisation pre-setting
• One feed system (monofeed)
Set the polarisation angle on the feed system according to
the value in the table for your location and the position of the
satellite from which the signal is to be received (see LNB user
instructions). For this the tiltable adaptor plate remains in the
zero position (see diagram on the right).
