The multi-switches meet the more stringent screening requirements according EN 50083-2, quality grade A. (The switches also meet the requirement of FCC part 15). All components are equipped with an earthing terminal for connecting to the main potential equalization. The multiswitch is equipped with an adjustable attenuator in order to adjust the level of the terrestrial or CATV signals. The input levels can be reduced in active operation by 0 … 10 dB. All the terrestrial signals can be passively distributed in the multiswitches.
