Abstract
L'apparecchiatura di radionavigazione N.D.B. portatile รจ composta dai seguenti accessori facenti parte integrante del sistema di emissione omnidirezionale dei segnali radio. Antenna portatile a raggiera con supporto magnetico per fissaggio su superfici metalliche, antenna fissa a doppia raggiera con supporto ad incastro per palo di prolunga, antenna filare con relativi isolatori, sistema voice per trasmettere nominativo stazione trasmittente o altri messaggi. Campo di applicazione dai 200 Khz ai 535 Khz. Funziona sia in corrente alternata con alimentatore che con corrente continua a 12 V da batteria auto. Risponde ai requisiti emanati dalle norme ICAO, Annesso 10, Vol.1, Parte1, Sez. 3.4. Le antenne in particolare sono formate da stilo che possono essere retratte e quindi occupare poco spazio.Peso dell'apparecchiatura N.D.B. circa 5 Kg. Ingombro 38x25x23 cm.The radio navigation equipment N.D.B. The handset is made up of the following accessories that are an integral part of the omnidirectional radio signal emission system. Portable ray antenna with magnetic support for fixing on metal surfaces, fixed double ray antenna with interlocking support for extension pole, wire antenna with relative insulators, voice system to transmit the name of the transmitting station or other messages. Field of application from 200 Khz to 535 Khz. It works both in alternating current with power supply and with 12 V direct current from car battery. It meets the requirements issued by the ICAO standards, Annex 10, Vol.1, Part1, Sec. 3.4. The antennas in particular are made up of stylus which can be retracted and therefore take up little space. about 5 Kg. Dimensions 38x25x23 cm.
