●
The metal parts must not form closed loops or circuits. If necessary, these must be
electrically interrupted at one point
.
● The metal parts in the immediate vicinity of the antenna must be grounded in a mesh with
a good HF connection.
● Since the write/read device is installed in a metal housing, and the antennas can couple
into the cables to the write/read device, it must be installed at a distance of at least 500
mm from the antennas.
Notes on installing and laying the antenna cable
To suppress possible interference, an EMC hinged ferrite choke must be fitted to the
antenna cables (as well as the antenna cable between the reader and the antenna splitter).
The coaxial cable must be wound tightly at least four times through the EMC ring core. The
maximum distance between the connecting plug for the reader or the antenna splitter and
the ring core must be 100 mm.
The antenna cable must always be run vertically from the antennas. A minimum distance of
200 mm to the antennas must be observed as the cables continue. Otherwise, performance
losses must be expected.
There must be a distance of at least 300 mm between antenna cables and parallel power
cables.
Unrequired cable length must be secured in a bundle with a diameter of 100 to 150 mm.
If the standard antenna cable is too short, it can be increased by 7.20 m with the extension.
Slight range losses must be expected here.
To achieve optimal read ranges, the antenna cable should not be shortened or lengthened.
