Abstract

Un sistema de antenas desmontables, caracterizado por la combinación de una línea de transmisión relativa mente rígida, de dos conductores, ramas de antena relativamente rígidas aseguradas a la referida línea en puntos espaciados, estando los referidos puntos a una distancia tal de los extremos de los conductores de la línea, a la frecuencia operativa, como para producir una impedancia reactiva de neutralización, y placas conductivas aseguradas a los referidos conductores en sus extremos, estando las placas unidas separablemente a una estructura de soporte.
