4.2 Height requirements
Antennas (without tilt) in a transmission path are to be placed at an appropriate height. The larger the opening angle, the larger the possible height offset.
4.3 Antenna alignment
Ideally, you need to direct the antennas in a transmission path in parallel to each other, e.g. all vertical and never head-to-head (see also 2.2 The radiation characteristics of an antenna).
4.4 Radiation
When mounting antennas please be aware of their opening angles and the need for overlap.
4.5 Separation and free radiation
To avoid radiation disturbances and reflections do not install antennas close to metal parts, engines or frequency converters.
4.6 Line-of-sight connection
The antennas in a transmission path should have line-of-sight connection, to ensure optimal
data transfer quality (see 2.7 Fresnel zone).
4.7 Get out of the control cabinet
Please mount the antennas outside the control cabinet. If made of metal the cabinet causes a significant damping of the transmission signal, thus reducing transmission reach. If the control cabinet is made of synthetic material you can place the antenna inside the cabinet, as this material only has low impact on signal strength.
4.8 Wall mounting
To achieve the best result mount directional antennas on a wall. If you request the characteristics of an omnidirectional antenna and if short reach is required you can wall mount an mnidirectional antenna as well. Wall mounted omnidirectional antennas cause reflections that reduce ransmission quality and reach.
4.9 Mast mounting
Montieren Sie Rundstrahlantennen idealerweise freistehend, z.B. an einem Mast, um auf horizontaler Ebene gleichmäßig in alle Richtungen abstrahlen zu können.
4.10 Consider the protection class (IP)
When you are installing outdoor antennas, please note that water must not be allowed to get inside the antenna. Furthermore you have to consider the protection class of the particular antenna you want to install.
4.11 Polarization
Antennas in a transmission path should ideally have similar polarization. Exception: For specific applications it can make sense to combine an antenna with a clockwise polarization – as a fixed station antenna – with a vertical polarizing antenna mounted on a mobile turning object.
4.12 Use of mounting material
Please use the mounting accessories offered by us, for the optimal positioning and orientation of directional antennas. The mounting materials match our antennas. By combining two mounting brackets (10519) you can pivot the antenna bilaterally.
