General Information
Please note:
As a result of more stringent legal regulations and judgements regarding product liability, we are
obliged to point out certain risks that may arise when products are used under extraordinary operating
conditions.
The mechanical design is based on the environmental conditions as stipulated in ETS 300 019-1-4 and thereby
respects the static mechanical load imposed on an antenna by wind at maximum velocity.
Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain caused by
oscillating support structures), may result in the breakage of an antenna or even cause it to fall to the ground.
Cylindrical bodies can show crosswind response, which can cause the supporting structure to oscillate and
to be damaged. Prismatic bodies, even with non-circular cross-section can show crosswind response, which can
cause the supporting structure to oscillate (see EN 1991-1-4 or EN 1993-3-1).
The installation team must be properly qualified and also be familiar with the relevant national safety
regulations.
The details given in our data sheets have to be followed carefully when installing the antennas and
accessories.
The limits for the coupling torque of RF-connectors, recommended by the connector manufacturers must
be obeyed.
Any previous datasheet issues have now become invalid.
Our quality assurance system and our environmental management system apply to the entire company and are
certified by TÜV according to EN ISO 9001 and EN ISO 14001.

The maximum wind velocities listed should be understood in the sense of working values according to DIN and
EN standards. These values include a safety factor (1.5) below the ultimate limit state (elastic limit or permanent
deformation). For these wind velocities we guarantee the mechanical safety and the electrical integrity of our
antennas.
Subject to alteration.
These facts must be considered during the site planning process.
