BECKHOFF CU8890-0000 - Manual (Page 18)

Operating Instructions
Alignment examples
Align the antennas so that each lies within the radiation cone of the
opposite antenna.
Omni directional antennas
Two ZS6201-0410 or ZS6201-0500
Directional antennas
Two ZS6100-0900
Mixed operation
e.g. one ZS6201-0410 and two ZS6100-0900
Polarization
For optimum transmission, all antennas used must have the same
polarization.
Omni directional antennas
Care must also be taken when using omni directional antennas that the
antennas used have the same polarization.
Omni directional antennas such as the ZS6201-0410, ZS6201-0500 or
ZS6200-0400 are mostly mounted for vertical polarization.
Directional antennas
Arrows marked with the letters H and V are located on the rear side of the
housing of the ZS6100-0900 directional antenna in order to identify the
polarization
Mount the directional antennas such that the marked arrows of all the
antennas used correspond to one another.
Placement of the antennas
Mount the antennas such that they can radiate freely!
There must be no obstructions in the direct vicinity of the antenna that
could hinder the development of the Fresnel zone. Metal obstacles such as
control cabinets, machine parts, pipelines, iron beams etc. particularly
hinder the development of the Fresnel zone!
The connection of the antennas to the CU8890 via the RSMA plug and
coaxial cable enables the antenna to be mounted remotely, so that you can
position the antenna optimally.
