Abstract

ANTENA MULTIFRECUENCIA PARA RADIOCOMUNICACIONES.SE ARBITRA LA VARIACION DE LA INDUCTANCIA Y LA CAPACIDAD, INDISTINTAMENTE O A LA PAR, SEGUN EL AJUSTE REQUERIDO, DE CADA UNO DE LOS ELEMENTOS (1) RESONANTES DE LA ANTENA, A TRAVES DE UN CONJUNTO ELECTROMECANICO (2). ESTE, ACCIONADO DESDE UN PUPITRE DE MANDO Y A TRAVES DE UN MOTOR, PRODUCE EL DESPLAZAMIENTO DE DICHO ELEMENTO PARA OBTENER DICHAS VARIACIONES DE INDUCTANCIA Y CAPACIDAD, CON LO QUE ES POSIBLE CUBRIR TODAS LAS BANDAS Y FRECUENCIAS, Y AJUSTAR ESTAS EN EL PUNTO EXACTO DE TRABAJO.
