a coaxial cable and high-gain antenna.
If the antenna is removed and re-installed or a cable is attached for a remote antenna,

Install the antenna outside the control cabinet or building.
Observe the installation instructions of the antenna and the “Installation and operation” on
Observe the maximum permissible emitted transmission power of 36 dBm. The
transmission power can be calculated as:
device transmission power + antenna gain - cable attenuation
Reduce the device transmission power, if necessary.
