Decoder DRG-07 is intended to renew group coded radio signal in cable networks, where channels MMDS are used for TV program delivery, with the radio signal transmitting according to the State Branch Standard 7845.
    Constructively the decoder is made as a leakless aluminium frame, into which in a case of necessity a trunk amplifier can be set.
    Decoders are controlled by video data, created by the coders and transmitted through one of TV channels of the grouped coded signal.
    Decoder power supply is fulfilled from the electricity supply network 220 V, 50 Hz. Decoder DRG-07 is set between an output of receiving MMDS converter and an input of the cable network amplifier.
    Decoder has to provide capacity for work by ambient temperature from +1°С to +40°С, atmosphere pressure 630-800 mercury mm and relative humidity not more than 80% by 25°С.
