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 inclination
(elevation) until the measured results or the picture 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 suffer damage in the wind.
b) 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 alignment 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 prevent the
antenna turning.
