3. Before you
begin to install, connect or utilize the antenna, observe
the information you find in these mounting instructions. If
you fail to pay attention to the information, one cannot
exclude
G that due to wrong installation and connecting, or
because of having modified components or using
other components, the antenna or the mounting place
will be dammaged.
G that because of inappropriate behaviour, risks for your
and other people's health and life will be created
G that the manufacturer will decline the liability for faulty
function and resulted dammages.
It is most important that you are aware of the responsibi-
lity you have for your own and other people's safety
when working on the antenna system.
Advice: Retain these instructions for possible later use
when questions come up. In case you sell the antenna
hand on the instructions to the new owner.
Attention!
Never install the antenna below overhead power lines.
It can be that the required safety distance is not kept.
Furthermore, make sure that the lateral distance to all
other electrical systems is at least 1 m.
Danger to life exists if you or the antenna make
contact with live parts.
Do not install the antenna on buildings with easily in-
flammable roofs (straw, reed or similar material). It
exists fire hazard since the antenna is subject to static
charge and lightning.

4. Mounting site
The selection of the right mounting site for your antenna
is important in order to ensure safe and satifactory
operation. When choosing the mounting site, pay
attention to typical characteristics of the building. If the
antenna is installed on the edge of a roof or building, one
must reckon acc. to DIN 1055, Part 4 or 4131 with a
higher wind or oscillation load. This means that the
dynamic characteristics of the antenna and the building
can influence each other and change the characteristics
negatively. Disregard of these circumstances can lead to
exceeding the max. load or dynamic strength mentioned
in sect. 2.
It is not essential to mount the parabolic antenna on the
roof since it is not height above ground that matters but
an unimpeded line-of-sight to the satellite. Thus a
suitable mounting location may be found in the garden,
on the balcony/terrace or on a facade or garage, for
example.
Thus, if at all possible, the roof should be avoided as a
mounting location. In any event this reduces the amount
of work and avoids the dangers of doing installation
work on the roof!
For good reception the antenna must have an unob-
structed „visibility" to the south (+/-20).
The horizontal elevation angle must be 30°.
The reception of the following satellites will then be
possible:
1 TÜRKSAT 1C
2 ASTRA 2-Group
3 ASTRA 3-Group
4 ASTRA 1-Group
5 EUTELSAT II F1
G Unobstructed „visibility" means that there must be no
obstacle (such as trees, buildings, roofs, balconies or
similar obstacles) between the antenna and the satelli-
te. Obstacles of this kind can impair the reception or
even make reception impossible.
