Our active antennas provide a remote receiver unit for time signal transmitters and after reception, deliver a demodulated output signal. The antennas are flexible as a result of their wide operating voltage range. The small and robust housing is easy to attach to the wall. Special cable length assemblies are possible. Some antenna variants are equipped with a selective input filter to guarantee reception in high-noise environments. Other active antennas have an internal quartz clock with automatic radio time synchronization. These models provide a reception-independent demodulated output signal with transmitter compliant second marking. The status indicator is visible via an LED. The latest variant "Intelligent Active Antenna II" has a housing with IP65 protection and is thus protected against dust and water spray.
