تقسیم کننده 4 اکتیو کد 4446
If several DCF77-clocks are wanted in the building the 4x antenna amplifier with potential separation can be used. The device is structured like the antenna amplifier FG444400, but without indirect lightning protection.
The housing contains the mains unit and several amplifier modules.
The signal is fed via a pre-amplifier to 4 potential free output steps and put out via insulated BNC-connectors on the wider side of the housing.
