Abstract

ESTA ANTENA , EN PARTICULAR DESTINADA A LA EMISION DE SEÑALES DE RADIODIFUSION O DE TELEVISION EN LA BANDA DE LAS ONDAS DECIMETRICAS, COMPRENDE : -UN TUBO SOPORTE CENTRAL (100), VERTICAL, -UNA PLURALIDAD DE REDES RADIANTES (200) IDENTICAS, PREFERENTENMENTE TRES, REGULARMENTE REPARTIDAS ALREDEDOR DEL TUBO CENTRAL Y FORMADAS CADA UNA DE UNA LINEA BIFILAR VERTICAL (210,210'') SOPORTANDO, ACOPLANDO Y ALIMENTANDO DE MANERA SIMETRICA UNA PLURALIDAD DE DIPOLOS HORIZONTALES (220,220'') REGULARMENTE REPARTIDOS A LO LARGO DE ESTA LINES BIFILAR, Y -UN SISTEMA DE DISTRIBUCION DE POTENCIA EQUIFASE EQUIPOTENCIA, ENTERAMENTE ALOJADA EN EL INTERIOR DEL TUBO SOPORTE CENTRAL, ALIMENTANDO IDENTICAMENTE Y SIMULTANEAMENTE LAS TRES REDES RADIANTES A PARTIR DE UNA LINEA DE ALIMENTACION COAXIAL UNICA. LA ANTENA ESTA DESPROVISTA DE REFLECTOR, LO QUE REDUCE DE MANERA IMPORTANTE SU PESO Y SU PRECIO A LA VENTA EN RELACION A LAS ANTENAS CLASICAS DE PANELES GENERALMENTE UTILIZADAS EN ESTA BANDA. VENTAJOSAMENTE, ESTAS ANTENAS ESTAN SUPERPUESTAS Y ENCERRADAS EN UN RADOMO ESTANCO, SENSIBLEMENTE CILINDRICO, AUTOPORTADOR Y SUPERCOLOCABLE. ESTA ANTENA PROCURA UN DIAGRAMA OMNIDIRECCIONAL A 0,9 DB ENTRE 460 Y 860 MHZ, Y PUEDE IRRADIAR 5 A 7 KW POR ELEMENTE DE ANTENA.
