Description
Cascadable multiswitches for 4 polarities and terrestrial TV with 12 outputs.
The outputs are amplified in the satellite IF band.
In the terrestrial band they can be configured to function  in either active or passive mode.
Need to be powered from each individual receiver so that the switching and amplification of each derived output will function. 

Applications
Medium-sized collective satellite and terrestrial TV installations.
It is essential that they be mounted along with end multiswitches, so as to obtain distributions of up to 64 outlets on a single line if they are installed with intermediary amplifiers.

Characteristics
Shielded metal chassis with plastic supports. F-type connectors. Earth.
