Abstract

DISPOSITIVO DE ANTENA DE TRES BANDAS PARA AUTOMOVILES QUE INCLUYE UN MASTIL (10) REALIZADO CON DOS TUBOS DE ANTENA CONECTADOS COAXIALMENTE Y DESLIZANTES (11,12), UNO DE LOS CUALES ANULA UNA CORRIENTE DE FASE INVERTIDA PARA EL TELEFONO, Y UN TUBO PARA LA COLOCACION DE LA ANTENA (13) QUE ALOJA EL MASTIL DE LA MISMA (10) DE FORMA QUE EL MASTIL (10) SE RETRAE DENTRO DEL TUBO Y SALE DE EL. EL DISPOSITIVO DE ANTENA INCLUYE ADEMAS UN SEPARADOR (81,82) QUE ESTA CONECTADO A UNA SECCION DE ALIMENTACION DEL TUBO DE ALOJAMIENTO DE LA ANTENA (13) PARA SEPARAR TRES BANDAS, A SABER: TELEFONO, FRECUENCIA MODULADA Y ONDA MEDIA, Y UN MONTANTE (14) DE PLASTIC PARA MONTAR EL TUBO DE ALOJAMIENTO DE LA ANTENA (13) EN LA CARROCERIA DEL (15) DEL VEHICULO. LA DISTANCIA DE RECORRIDO ELECTRICO ENTRE EL CONDUCTOR EXTERIOR DE CABLE DE ALIMENTACION (21) Y LA CARROCERIA DEL VEHICULO (15) ES 0 A X/2 DE FORMA QUE LA IMPEDANCIA DEL CIRCUITO DE TIERRA ES CERO.THREE-BAND ANTENNA DEVICE FOR AUTOMOBILES INCLUDING A MAST (10) MADE WITH TWO COAXIALLY CONNECTED AND SLIDING ANTENNA TUBES (11,12), ONE OF WHICH CANCELED AN INVERTED PHASE CURRENT FOR THE TELEPHONE, AND A TUBE PLACEMENT OF THE ANTENNA (13) WHICH HOUSES THE MAST OF THE SAME (10) SO THAT THE MAST (10) RETRATES WITHIN THE TUBE AND COMES OUT OF IT. THE ANTENNA DEVICE ALSO INCLUDES A SEPARATOR (81.82) THAT IS CONNECTED TO A SUPPLY SECTION OF THE ANTENNA HOUSING TUBE (13) TO SEPARATE THREE BANDS, TO KNOW: TELEPHONE, MODULATED FREQUENCY AND MIDDLE WAVE, AND A MONTANT (14) OF PLASTIC TO ASSEMBLE THE PIPE OF ACCOMMODATION OF THE ANTENNA (13) IN THE BODY OF THE (15) OF THE VEHICLE. THE DISTANCE OF ELECTRIC TRAVEL BETWEEN THE OUTDOOR POWER CORD CONDUCTOR (21) AND THE VEHICLE BODY (15) IS 0 TO X / 2 SO THAT THE IMPEDANCE OF THE GROUND CIRCUIT IS ZERO.
