6. Mounting site
Attention!
• Never install the antenna below overhead power lines. It is possible that the required safety
distance is not kept. Furthermore, make sure that the lateral distance to all other electrical sy-
stems is at least 1 m.
Danger to life exists if you or the antenna come into contact with live parts.
• Do not install the antenna on buildings with an easily infl ammable roof (straw, reed or similar
material). Fire hazard exists since the antenna is subject to static charge and lightning.
The selection of the right mounting site for your fl at antenna is important in order to ensure safe and satisfactory
operation. Therefore, observe the following:
a) ”Visibility“ of the satellite
The antenna must have an unobstructed ”visibility“ to the south (+/- 20°).
A few satellites (e. g. TÜRKSAT 1C, HISPASAT 1A/1B) require an angle larger than +/- 20° looked at from the
south (Azimuth). The horizontal elevation angle must be 30°.
Unobstructed ”visibility“ means that there must be no obstacle (such as trees, buildings, roofs, balconies or simi-
lar obstacles) between the antenna and the satellite.
Obstacles of this kind can impair the reception or even make reception impossible.
b) Secure installation
The decisive factor for choosing the mounting site for your fl at antenna is not – when compared with a standard
receiving antenna – the installation height above ground, but the unobstructed ”visibility“ of the satellite. This
means that the installation need not effected on the roof of a house.
The antenna can be installed in the garden, on a terrace, on a balcony, on a facade or on a garage.
Therefore, if other possibilities for the installation exist, do not install on the roof. It will mean less work for you
and additionally, the dangers connected with working on a roof are much smaller.
Attention
• The installation work can create problems for your health and life.
Therefore:
• The mounting procedure described here demands skill and a knowledge of how the antenna
behaves when being exposed to atmospheric conditions. If you don´t have the required qualifi -
cations, ask a specialist to do the installation work.
• When working on the roof or near to drop–away sites, use a safety belt.
• Make sure that the roof will support your weight. Wear non-slip shoes.
• Only use ladders or other climbing aids that are in perfect condition.
• If passers-by can be hurt by parts falling down, block the dangerous area.
• Watch out for overhead power lines. Contact with these means danger to life!
• Never work on antenna systems when there is a thunderstorm – Danger to life!
