Repeater radio station assembly

Technical parameters


The repeater radio station assembly is installed in REG-F to establish radio communication with mobile radio stations.

The station structure includes two units:

- a radio station unit consisting of two radio stations (receiver and transmitter), a duplex filter and a lightning protection module;

- the radion station starting unit  RSSU4-R.
