    - Downconverter
      - Introduction
        The Real Freedom Downconverter is a key component of BSI’s Real Freedom wireless camera system. It receives signals in the broadcast transmit band and down-converts them to a UHF signal of between 50 MHz and 850 MHz. The UHF signal is then fed to a receiver via a coaxial cable.
      - Installation and configuration
        Designed to be compact and fully weatherproof, the Real Freedom Downconverter can be temporarily installed almost anywhere or permanently on the roof of an outside broadcast van.
      - Operation
        Once connected to the system and configured, no further changes are required to the downconverters during the routine operation of the Real Freedom system.
      - Troubleshooting
        This chapter provides troubleshooting information for Real Freedom Downconverters.
