together with mast components from a specialist supplier (tube
in steel grade St 52 with outside diameter 60 mm and wall
thickness 2.5 mm at the mast clamping point – e.g. ZSH 59
from Kathrein).
If you arrange the structure differently you must calculate wind loading and bending moment at the
clamping point as specified in DIN EN 60728-11 (or have a specialist do the calculation for you).
c) 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 elevation 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
finger-tight.
(The fine adjustment of the elevation will be performed later.
See the section "Aligning the antenna")
• Now secure the carrier arm to the mast tube/boom by
tightening the wing nuts. Tighten the nuts initially only finger-
tight and check that the alignment of the carrier arm is
generally towards the south.
• Now hold the boom of the carrier arm firmly 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).
