Setting the direction (azimuth)
If you yourself are unable whilst performing the adjustments
to read the results of the alignment work on an
antenna
meter
or
screen
connected to the satellite receiver, you may
need an assistant for the following steps. The precise align-
ment of the antenna can be achieved only if a digital antenna
meter is used. Ask your dealer about this.
– Set the satellite receiver to a known channel so that you
can check that you have really “locked on” to the desired
satellite.
– Now slightly loosen the wing nuts on the mast clamp.
– Twist the antenna so that it faces roughly south. Then
slowly twist the antenna about its central axis to left and
right until the best reception is obtained for the selected
channel.
– Then tighten the
wing nuts
initially just enough to pre-
vent the antenna turning.
c.
Fine adjustment
– Once again slacken the bolt on the inclination scale and
tilt the antenna lightly upwards and downwards until
either the antenna meter shows the strongest antenna
signal or visual assessment is judged to achieve the best
picture: To do this, tilt the antenna far enough upwards
and downwards to get to the limits when the fi rst “little
fi sh” (analogue) or “little blocks” (digital) appear on the
screen. Position the antenna midway between the two
limit points.
– Now alternately correct the direction (azimuth) and inc-
lination (elevation) until the measured results or the pic-
ture quality show no further improvement.
Note:
Tightening the nuts at the clamping piece can cause
the antenna to turn slightly! You should allow for this at
the fi ne adjustment stage (and if necessary make use of
it when starting the adjustment operation all over again).
d.
Finally tightening the antenna clamps
– Then tighten the nuts at the
clamping piece
by hand,
working across diagonals. Then use a 13 AF open-ended
spanner to tighten up each of the wing nuts one turn.
– After this, tighten the bolts on the
left and right
of
the clamp of the
inclination scale
, using the hexagon
key
fi rst with the short end
to tighten them fi nger-
tight and then with the
long end
tighten them a further
1/4 – 1/2 turn
(torque wrench: 4 – 5 Nm).
–
Finally check
once again that the bolted connections are
secure.
– Attach the cables to the carrier arm by clipping them into
the cable clips within the carrier arm and use
cable ties
to secure them all along the antenna carrier, so that they
cannot chafe and suff er damage in the wind.
