• For good reception, an unobstructed “view” in the direction of
the reception must be ensured, at an elevation of about 30°.
The following satellites are then available for selection:
• Do make sure that there are no obstacles between the parabolic
antenna and the respective satellite (such as trees, roofs, house
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 48
and 90 mm, with a wall thickness at least 2 mm. For
wall
installation,
Kathrein recommends the use of ZAS 62 or
ZAS 63 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. Suf
fi
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).

the extent that during unfavourable stormy weather the signal
is lost altogether.

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).
