INSTALLATION SITE SELECTION GUIDELINES
It is essential to select the correct installation site. This determines whether your parabolic antenna can be erected
safely and perform optimally. When selecting the installation site, take account of special features of the structure
of the building. If the installation is at the edge of the roof or the building or on a cylindrical structure, DIN 1055,
parts 4 and 4131 specify the increased wind and vibration loadings that should be allowed for. The dynamic
properties of the antenna and the structure can mutually influence each other and cause detrimental changes.
Disregarding these considerations can lead to excessive load or vibration fatigue stress. The parabolic antenna
need not necessarily be mounted on the roof, since the requirement is for an unobstructed (line of sight) “view” of
the satellite. For this reason, an appropriate installation site might also be found for instance in the garden, on the
terrace, on the face of the building or on a garage. In fact if other sites are possible, it is better to avoid the roof.
This will result in less work for you and will reduce the hazards associated with installation work on the roof! 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:
10° East EUTELSAT W 1
13° East EUTELSAT HOTBIRD
16° East EUTELSAT W 2
19.2° East ASTRA 1 group
23.5° East ASTRA 3 group
28.2° East ASTRA 2 group
30° West HISPA-Sat
42° East TÜRKSAT
Please 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 unfavorable
stormy weather the signal is lost altogether.
INSTALLATION MECHANICAL GUIDELINES
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 on the antenna carrying structure
• 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 35 and 60 mm of about 3mm thickness.
• 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 specifications.
Note: 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).
