Multi-feed
adaptor plate
e. Feed system (LNB)
Tip
For multi-feed applications the antenna should be
aligned towards the satellite which is transmitting the
weakest signal level.
Tip
The optimum performance of the satellite antennas
is only given in conjunction with the original Kathrein
LNBs, because this is the only way to ensure optimum
illumination of the reflector.
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.
Using the
multi-feed adapter plate
on the carrier arm you
can install one or two Kathrein universal feed systems. The
markings on the adapter 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:
Position 2
Position 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
EUTELSAT 10° East
EUTELSAT 7° East
●
Example for the installation positions for a multi-feed
application with
6° satellite spacing
:
Position 1
Position 5
ASTRA 19.2° East
EUTELSAT 13° East
EUTELSAT 16° East
EUTELSAT 10° East
EUTELSAT 13° East
EUTELSAT 7° East
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 adapter plate remains in the
zero position (see diagram on the right).
