ANTENNAS

8.2.7.1 INTERNAL ANTENNAS
The DECT base station is equipped as standard with two quarter-wave antennas integrated
into the unit. The antenna diversity feature enables the system to automatically select the
better of the two antenna signals.
8.2.7.2 EXTERNAL ANTENNAS
To replace the integrated antennas with one or two external antennas, a connection kit is
available for the connection between the radio base stations and the external antennas.
If only one external antenna is used, the antenna diversity base station feature can be
disabled by MMC.
Three types of antenna can be used in the DECT base station They are available from
MAT Equipement.

HT6176A
A 50-centimeter cable equipped with a male TNC connector is provided with the dual and
directional antenna (MA821X12). To maintain the gain/directivity of this antenna, additional
cables between it and the base station should not be inserted. The radiating element
therefore has to be placed in immediate proximity of the base station.
Conversely, a remote connection must be used for the other two antennas (MA431X02 and
MA431X03). This must not be detrimental to the radio link (for further details, refer to the
external antenna installation guide provided in the connection kit.
