Tighten by hand
Fully tighten: 1 ½ turns
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 (
④
).
–
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: 5 – 10 Nm) (
⑤
).
–
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.
