Aligning the Antenna
The antenna must be exactly aligned towards the satellite in
respect of both the direction (azimuth) and also the inclination
(elevation). For multi-feed applications the antenna should be
aligned towards the satellite which is transmitting the weakest
signal level.
a) Setting the inclination (elevation) (if not already set under
“Installing the carrier arm”)
• Use the hexagon key supplied with the parabolic antenna
to slacken the two screws on each side of the inclination
scale (elevation) on the left and right of the support.
• Then adjust the inclination (elevation) – the exact elevation
angle for your location can be found in the manual for the feed
system (LNB).
• When doing this, retighten fi rst just one of the bolts on the
inclination scale fi nger-tight.
• 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
level.
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).
• Multiple feed systems (multi-feed)
For the multi-feed arrangement the tiltable support should be
tilted to the angle “V” as shown in the azimuth/elevation table
for multi-feed applications, supplied. In this case the polarisation
angle on the feed system should be set not to the value in this
table but in accordance with a calculated correction angle:
PW
NEU
= PW
TAB
- V
In order to be able to tilt the support you must fi rst use
the hexagon key to slacken the bolt shown arrowed in the
illustration on the right.
