DCF77-antenna amplifier

4-times antenna amplifier FG444400 and FG444600

If several DCF77-clocks are needed in the building, it is possible to use the 4-times antenna amplifier with potential separation. The devices FG444100, FG444400 and FG444600 have all the same structure. The housing contains the mains unit and 5 amplifier modules.

The signal is transmitted to 4 potential free output steps via a pre-amplifier and put out via insulated BNC connectors on the wide side of the housing.

The 4-times antenna amplifier is available in two variations:

• the device FG444400 with an indirect ligthning protection.

• the device FG444600 without a ligthning protection (see picture).
