d) Installation of the parabolic antenna
• Now hang the parabolic reflector from the four securing bolts
on the carrier arm (see arrows in the diagram on the right).
• Now lightly tighten the four bolts using the hexagon key (do
this by holding the hexagon key by the short end, see diagram
on the right).
• Now turn the hexagon key round. If you now swing the long
end of the hexagon key (see diagram on the right) through
about a quarter of a turn, the bolts will be tight. If you have a
torque wrench available, tighten the bolts to about 4 – 5 Nm.
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.
• 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:

level.
