The Unifiber DTT Processing unit receives DAB/FM VHF and UHF DTT signals over two separate antenna ports and outputs a combined signal for optical distribution through a Unifiber Transmitter unit. The Unifiber DTT Processing unit is powered by the transmitter over the DTT output port. The unit features an adjustable attenuator allowing to control the level of the VHF signal. It also features a built-in UHF AGC for improved DTT signal quality and simpler installation process, freeing the installer from the need to manually optimize the DTT signal levels. A compact size robust die-cast housing and a weather-proof enclosure allow for either indoor or outdoor installations.

Main Features:
  • Supporting FM/DAB/VHF and UHF bands
  • Built-in UHF AGC for optimized performance and easy installation
  • Adjustable gain for VHF broadcasts
  • Powered by Unifiber transmitter over the DTT output port
  • Outdoor and indoor installations
