If you arrange the structure diff erently you must calculate wind loading and bending moment at the
clamping point as specifi ed in DIN EN 60728-11 (or have a specialist do the calculation for you).
domestic antennas together with mast components from
a specialist supplier (tube in steel grade St 52 with out-
side diameter 60 mm and wall thickness 2.5 mm at the
mast clamping point – e.g. ZSH 59 from Kathrein).

Installing the carrier arm
– Slacken the four bolts on the elevation scale, using the
hexagon key supplied with the parabolic antenna.
– Now set the elevation value to suit the satellite(s) to be
received and your actual location (see LNB manual). If
you have no data relating to your location, set an eleva-
tion value of approx. 35° for the carrier arm. The desired
scale value must be in the centre of the notch.
– Then use the hexagon key to tighten any two of the four
bolts fi nger-tight.
(The fi ne adjustment of the elevation will be performed later;
see the section
Aligning the Antenna
on p. 6.)
– Now secure the carrier arm to the mast tube/boom by
tightening the wing nuts. Tighten the nuts initially only
fi nger-tight and check that the alignment of the carrier
arm is generally towards the south.
– Now hold the boom of the carrier arm fi rmly and remove
the cable tie (see dashed circle in the diagram on the
right).
– Swing the carrier arm boom out and use the hexagon key
to tighten the two M6 bolts at the “wrist” of the carrier
arm to 4 – 5 Nm (see arrow in the diagram on the right).
