Please read the following safety instructions carefully and thoroughly before you start installing the antenna, and keep
observing them during the installation!
The installation of the antenna demands a high degree of responsability for yourself and other people. For this reason, the instal-
lation must be executed by an electrician (expert in his/her trade). In order to assist you, some important safety instructions have
been compiled in the following. However, these instructions are not exhaustive, as we are not aware of the local conditions.
►
Do not use the antenna for purposes other than intended by the manufacturer.
►
Only use the components as prescribed by the manufacturer and do not modify them.
►
When selecting the antenna site, take account of the building‘s structural characteristics. Installation on the edge of
cylindrical structures could lead to increased wind loads and vibration stress according to DIN 1055, part 4, DIN 4131.
Non-observance of these instructions may cause exceeding of the load limit or the vibration resistance.
►
Do not mount the antenna on buildings with rooftops made of easily infl ammable materials (e.g. straw, reed or
similar materials).
►
Only step on fi rm, dry rooftops and protect yourself against falling down
►
To ensure safety, ladders, scaff oldings, safety belts etc. must be in good structural order.
►
Passers-by must not be endangered by falling objects. Secure the work/danger area!
►
Ensure that the technical values (e.g. wind load) of the antenna mast are not exceed. Consult the manufacturer
if you do not know these values. See
„Suitable Kathrein masts“ on page 4
for an overview of the masts off ered by
KATHREIN Digital Systems.
►
Mount the antenna mast on solid ground only (walls, concrete, rafters) using the clamps, dowels and screws recom-
mended by the manufacturer
►
Immediately leave the roof in case of a thunderstorm!
Mast installation and mast calculation
•
Make sure masts is in vertical position when installing it
•
Only use masts or standpipes specially designed for antenna
installation. Other tubes mostly do not have the necessary
stability to withstand heavy wind or other climatical situations.
Kathrein masts and clamps fulfi ll these requirements. See
„Suitable Kathrein masts“ on page 4
for an overview of the
masts off ered by KATHREIN Digital Systems.
•
The clamping range of the AVH 06 masting clamps is 22 to
55 mm
•
If the mast is to be mounted on a roof, at least 1/6 of its length
must be clamped
•
Make sure that the mast holders (e.g. clamps) are mounted on
solid ground (wood, concrete, walls)
Never exceed the maximum load capacity of the
mast or clamps when mounting several antennas
on the mast.
The bending moment aff ects the mast on the
upper attachment point for all antennas. The wind
load on the mast must be included in the calcula-
tion.
The overall bending moment is not to exceed the
maximum permitted bending moment of the mast
and must not be greater than 1,650 Nm. If the
bending moment is greater, a static engineer is
required to provide verifi cation of the transfer of
forces into the structure of the building.
