  • Our unique distribution/branch system enables reception of high quality TV images.
    CATV, VHF, UHF, BS and CS transmission is available.

  • Wiring in the pipe shaft is greatly simplified.
    70% of work for installing the TV reception system is completed in the factory.
    The work period and cost can be drastically reduced.
