Installing The Antenna - Kathrein Euroline Series Manual

Offset Parabolic Antennas
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:

Make sure that there are no obstacles between the parabolic
antenna and the respective satellite (e.g. trees, roofs, house
eaves or other antennas). Such items or structures can impair
reception to the extent that during unfavourable stormy weather
no signals are received altogether.
The reception is dependent upon the respective location and the satel-

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.
Requirements for 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 30 and
90 mm with a wall thickness at least 2 mm. For wall installa-
tion, we recommend the use of Kathrein 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).
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 Tech-
nical Data. The maximum loading will not be exceeded if
you arrange your antenna system as shown in the example
bottom right, and use conventional domestic antennas
together with mast components from a specialist supplier
(tube in steel grade S 355 (St 52) with an outer diameter of
60 mm and a wall thickness of 2.5 mm at the mast clamping
point – e.g. Kathrein ZSH 59).
Notice
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).
