COFDM-modulator SFN front face

       * Transmitter DVB-T, H (2k, 4k, 8k, MFN or SFN mode)
       * Average power 100W
       * It consists of transmitter FTV-220D and COFDM-modulator SFN (when organizing single-frequency network)
       * If network is multifrequency (MFN) than modulator COFDM is included into composition of transmitter FTV-220D
       * Control of COFDM modulator's modes is exercised from computer
       * Automatic power control
       * Displaying of output power, antenna-feeder path VSWR, supply voltage and final stage temperatures + emergency operation          displaying when having an emergency
       * Protection of antenna-feeder path by VSWR
       * SFN mode
