c. Installing the carrier arm
–
Attach the carrier arm to the antenna boom as shown on
the drawing (
). When so doing, tighten the nuts at the
clamping piece only lightly (using for instance a 17 mm
open-ended spanner), until the carrier arm is sufficiently
securely clamped to the mast for further erection work.
The locknuts should not be tightened until final tighten-
ing of the antenna fastenings.
d. Installation of the parabolic antenna
–
Now hang the parabolic reflector from the four securing
bolts on the carrier arm (see the diagram on the right)
(
), but do
not fully tighten them yet
,
–
because the covering washers supplied must first be
attached (
). To do this, unscrew the four bolts one at a
time in turn - fit the covering washer to the bolt and screw
it back in.
–
Now lightly tighten the four bolts using the hexagon key
(do this by holding the hexagon key by the short end, see
diagram on the right) (
).
–
Now turn the allen wrench round. If you now swing the
long
end of the hexagon key (see diagram on the right)
through about a quarter of a turn, the bolts will be
tight
.
If you have a
torque wrench
available, tighten the bolts
to about
4-5 Nm
(
).
Tighten only lightly!
