Decoder DRA-07 is designed to give individual subscribers the possibility to view TV channels, which are scrambled by coders of the Conditional Access System "Crypton". Decoder is used in cable networks of the collective television reception, MMDS networks, other networks for transmitting radio signal according to the State Branch Standard 7845.
    Constructively subscriber decoder is made as a radio-electronic module in a shielding casing of polypropylene with dimensions 55*35*20 mm, which is equipped with F sockets to connect to the subscriber tap of TV network and television receiver. To connect to the video output of the television receiver RCA sockets with pipe-bend length not less than 500 mm are used.
