Abstract
"DISPOSITIVO DE DISTRIBUIçãO DE SINAL DE RáDIO E SISTEMA DE RECEPçãO QUE COMPREENDE O DITO DISPOSITIVO". A invenção diz respeito a um dispositivo de distribuição de sinal de rádio e a um sistema de recepção que compreende o dito dispositivo. Mais especificamente, a invenção propõe uma solução por meio da qual dados podem ser trocados entre dois decodificadores por meio do cabo da antena, enquanto que pelo menos dois decodificadores podem ficar posicionados em duas bandas de transmissão diferentes ou em duas antenas independentes. O dispositivo inventivo, que é usado para distribuir sinais em uma corrente de recebimento multidecodificador, compreende dispositivo de interconexão das entradas/saídas, que são ligados aos decodificadores, a fim de produzir um sinal um contato elétrico que é limitado a uma banda de freq³ência de comunicação. A invenção também diz respeito ao sistema de recepção que compreende um dispositivo de conversão como esse.
