5.10.2 Connection of external antenna coupling systems – Optionally, only
FlexibleTx variant
In the FlexibleTx variant, antenna coupling was performed project-specifically according
to the desires and requirements of the network operator via external antenna coupling
systems. In this way, the DIB-500 R4.1, e.g. can be connected to existing antenna cou-
pling systems.
Requirements for external antenna coupling systems.
The requirements on external antenna coupling systems are described in the site
requirements.
Figure 5.23 shows by way of an example the connection of an external antenna cou-
pling system to the FlexibleTx variant of the DIB-500 R4.1. The connections of external
antenna coupling systems to the DIB-500 R4.1 and to the antenna(s) are to be defined
to match the project.
