Abstract

"ARRANJO DE CONVERSOR DE FREQuêNCIA PARA ANTENAS PARABóLICAS". Arranjo de conversor de freq³ência para antenas parabólicas de recepção de sinais com polarizações lineares vertical e horizontal, emitido por dois satélites geoestacionários a pequena distância um do outro. O arranjo é do tipo que compreende dois dispositivos conversores (5, 6) destinados à recepção do sinal proveniente de um satélite, cada dispositivo portando meios que asseguram que os elementos de antena de recepção sejam orientados no plano do sinal recebido e meios adaptadores às elevações diferentes dos dois satélites, por rotação dos dispositivos conversores. O arranjo é caracterizado pelo fato de que as partes de saída (10) dos dois dispositivos conversores (5, 60 são realizadas sob forma de uma peça monobloco (12), enquanto que as partes de entrada (9) são separadas e montadas seletivamente orientáveis sobre a peça monobloco (12), o arranjo sendo montado rotativo em torno de um eixo paralelo às duas partes de entrada (9).
