Abstract
LA INVENCION DESCRIBE UNA INSTALACION DE DIVERSIDAD DE ANTENAS PARA LA RECEPCION MOVIL DE ONDAS METRICAS Y DECIMETRICAS. CONSISTE EN UN INTERRUPTOR (2A) SELECTOR DE ANTENA Y UN SINTONIZADOR (4A) AL QUE LA SEÑAL DE REFERENCIA SELECCIONADA ES TOMADA POR EL INTERRUPTOR (2A) SELECTOR DE ANTENA, DONDE EL SINTONIZADOR (4A) DISPONE DE UNA SALIDA QUE CONDUCE LA ZF DE LA SEÑAL DEMODULADA CONECTADA A UN PROCESADOR (9A) EN EL QUE SE EVALUA LA SEÑAL. DEPENDE DE LA EVALUACION DEL RESULTADO DE LA SEÑAL SI EL SELECTOR DE ANTENA SE DISPARA CON EL INTERRUPTOR A TRAVES DE LA LINEA DE CONTROL QUE SE DIRIGE DESDE EL PROCESADOR (9A) DE DIVERSIFICACION AL INTERRUPTOR (2A) SELECTOR DE ANTENA. EN ESTE EXTREMO SE ENCUENTRA UN DISTRIBUIDOR (1) DE ANTENA CON ENTRADAS Y SALIDAS, CUYAS ENTRADAS RECIBE DE LA SEÑAL DE ANTENA (A1, A2..AN) Y LA SEÑAL DE SALIDA (1,..N) DE LAS QUE SON TOMADAS EN EL INTERRUPTOR SELECTOR DE ANTENA. EL DISTRIBUIDOR DE ANTENA (1) TIENE AL MENOS UN JUEGO ADICIONAL DE SALIDAS (1,..N) SIENDO CONECTADO CADA JUEGO AL INTERRUPTOR SELECTOR DE ANTENA PROPIO (2A, 2B), LA SALIDA DEL CUAL SE CONECTA A SU PROPIO SINTONIZADOR (4A,4B). CADA SINTONIZADOR (4A, 4B) TIENE UNA SALIDA QUE CONDUCE LA SEÑAL ZF O SEÑAL DEMODULADA Y LO GUIA A UN PROCESADOR (9A, 9B) DE DIVERSIFICACION DE LOCALIZACION QUE EVALUA UNA SEÑAL ADAPTADA AL SINTONIZADOR ASIGNADO. EN LA BASE DE LA EVALUACION DE SEÑAL EL INTERRUPTOR DE SELECTOR DE ANTENA ASIGNADO (2A, 2B) ES CONTROLADO POR UNA LINEA DE CONTROL DE FORMA QUE TRANSMITE UNA MEJOR ENTRADA DE SEÑAL A SU SALIDA.
