Abstract
LA INVENCION SE REFIERE A UNA INSTALACION DE ANTENA PARA ESTACIONES DE RECEPCION-TRANSMISION DE BASE PEQUEÑA EN UN SISTEMA DE COMUNICACION DE RADIO PARA PARTICIPANTES MOVILES CON AL MENOS UN CANAL DE TRANSMISION Y RECEPCION OPERANDO EN FRECUENCIA SEPARADAS Y AL MENOS DOS ANTENAS DISEÑADAS PARA RECEPCION REDUNDANTE (RECEPCION DE DIVERSIDAD). CADA ANTENA SE UTILIZA COMO ANTENA DE TRANSMISION PARA AL MENOS UN CANAL. EN TRANSMISION NO REDUNDANTE, CADA ANTENA ES ALIMENTADA MEDIANTE OTRO CANAL DE TRANSMISION Y LA DIVERSIDAD DE RECEPCION ES TAL QUE AL MENOS UNA ANTENA ESTA AJUSTADA PARA LA RECEPCION DE UN CANAL QUE ESTA ASIGNADO AL CANAL DE TRANSMISION DE OTRA ANTENA. SE UTILIZA EN SISTEMA DE RADIO MOVILES, ESPECIALMENTE REDES D Y E. VENTAJAS: BAJO COSTE, BAJAS PERDIDAS DE TRANSMISION, ALTA FLEXIBILIDAD DE CANAL Y, SOBRE TODO, PREVENCION DE INTERFERENCIA DE SISTEMA MEDIANTE PRODUCTOS DE INTERMODULACION.
