External antenna
Preassembled standard cables in lengths of 1 m, 3 m, 5 m, 10 m, 15 m, 20 m and 40 m are
available to connect the antenna.
The read range is limited by the cable loss. The maximum range can be achieved with the
cable 6GT2815-0BH10 (length 1 m) since this has the lowest cable loss.
Examples of possible antenna reading point configurations
●
A data source with an external antenna for a reading point.
●
As an alternative, a data source with an internal antenna for a reading point.
