Tip Then laying the antenna cable it is important not to bend the cable,
causing irreparable damage (reduction in performance caused by a
change to wave resistance).
A "active antenna" is a RF receiver with integrated antenna. It communicates with
an actuator unit, for example, via a simply RS485 cable (RS485 Gateway). So that
no shielded antenna is required that suffers from reduced performance as the
length increases and that can be bent during installation.

11.5.5 Distances from receive to other sources of interference

EnOcean transmitters can be placed next to any transmitter without a problem.
Conversely, the distance from the EnOcean receiver to other transmitters (e.g.
GSM / DECT / Wireless LAN) and high frequency sources of interference
(computer, audio and video systems) must be at least 50 cm.
The distance of the EnOcean receiver to other high frequency transmitters
should be at least 50 cm.
The transmitter position is non-critical.
