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 first "little
fish" (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 incli-
nation (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 fine 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
first with the short end to tighten them finger-tight and
then with the long end tighten them a further 1/4 – 1/2
turn (torque wrench: 5 – 10 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.
