1.3 Connecting and Positioning of remote Antennae
The MCW-D 100 control unit can also be operated with remote antennae. Low attenuation connecting cables are available in
different lengths. Please note that all three antennae have to be connected remotely. The transmitting antenna should be mounted in
the centre and the receiving antennae on the left and right. The range can be increased by using a directional antenna (e.g. CA 2413,
gain approx. 6 dB).
Depending on the cable attenuation you should use antenna amplifiers if the cables are long (refer to table below).
Cable attenuation of different cables in various applications
RG 58
RG 213 U
Aircell 7, CA 2420
Ecoflex, CA 2430
We recommend to use the CA 2441 antenna amplifier if the cable attenuation exceeds 12 or 15 dB, i.e. if the CA 2420 cable is longer
than 40 m or the CA 2430 cable is longer than 60 m.
Important Note:
To comply with FCC RF exposure compliance requirements, the following antenna installation and device-operating configuration
must be satisfied. Only authorized and certified beyerdynamic systems integrators may perform the installation of antennae.
There are no user serviceable parts or processes. Connect the receiving antennae to the antenna inputs (5) A and B. Connect the
transmitting antenna output (12). To maintain compliance with the FCC's RF exposure guidelines, this transmitter and its antenna must
maintain a separation distance of least 20 centimetres from all persons.
