For good reception, an unobstructed "view" to the south
(+/- 20°) must be ensured, at an elevation of about 30°. The
following satellites are then available for selection:
1 TÜRKSAT
42° East

2 ASTRA 2 group
28.2° East
3 ASTRA 3 group
23.5° East
4 ASTRA 1 group

5 EUTELSAT W 2
16° East
Do make sure that there are no obstacles between the
parabolic antenna and the respective satellite (such as trees,
roofs, house eaves or other antennas). Such items can
impair reception to the extent that during unfavourable stormy
weather the signal is lEast altogether.

The reception is dependent upon the respective location and the satel-
lite coverage zone
Installing the antenna
When installing the antenna carrier (mast or wall boom), ensure
that it is standing upright. Otherwise, there may be problems with
the alignment of the antenna to the satellites.
a) Requirements on the antenna carrier
Use only masts or support tubes that are specially designed
for installation of antennas. Other tubes generally do not
have the strength required to withstand the forces of wind and
weather.
For mast installation, select a tube diameter between 32 and
60 mm (for CCA 600x) or between 48 and 76 mm (for CCA 750x/
CCA 850x) with a wall thickness of at least 2 mm. For wall
installation, CityCom recommends the use of Kathrein's
ZAS 60 or ZAS 61 wall brackets.
For mast installation on a roof, the mast must be clamped for
at least 1/6 of its free length (in the example bottom right this
is 0.7 m).
b) Several antennas on a single antenna carrier:
Install the parabolic antenna as far down the mast as
possible, so as to minimise the bending moment at the
clamping point.
Under no circumstances exceed the maximum value for
the loading on the mast or mast support, as stated in the
Technical Data. Suffi cient cognizance of the maximum
loading is achieved if you arrange your antenna system as
shown in example bottom right and use conventional domestic
antennas together with mast components from a specialist
supplier (tube in steel grade St 52 with outer 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 specifi ed in DIN EN 60728-11 (or have a specialist do the calculation for you).
