6.3.6 CONNECTIONS
This section shows the connections to be made and the characteristics of the material to be used.
The MBS Unit is a weather-protected device once the equipment has been installed in its final location; make
sure that there is no MBS Unit connector without plug or cable connected. Besides, the external wiring
connections of the MBS Unit must be protected from weather, (vulcanizable tape can be used if it is
necessary).
To connect two MBS Units you must have the interconnection kit for additional carrier (Cod.
D014001PT). This is obtained as an independent accessory. In the following table is showed the connection
between two MBS Unit using the interconnection kit

For MBS units without duplexer (O148051), the following external filter must be installed:
Frequency range
Attenuation in RX relative to
the pass band
Attenuation in TX relative to
the pass band
380 – 470 MHz
80 dB @ TX band
60 dB @ offset
(1)
> 10 MHz
80 dB @ RX band
60 dB @ offset
