1.3 Connecting and Positioning of remote Antennae
The MCW-D 200 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.
• Size of the room: up to 400 m 2 (20 x 20)
• Number of participants: 30 - 100
• Antenna position: The antennae should be placed as high as possible above the table
in a position close to the participants.
• Alignment: Place the antennae so that they point to the participants (the convex side must point to the front).

Installation with remote antennae for normal Meetings
The CA 2413 planar antenna is connected to the MCW-D 200 control unit and mounted onto a stand with the CA 2462 mounting
kit For more information refer to the “MCW-D Design Guide”.

Important:
• There must be an unobstructed path between the microphone units and the antennae . The range is around
30 m . For optimum range the surface of the table is important, wood or plastic tables are ideal, but metal tables can
cause interferences and reduce the range.
