DESCRIZIONE DESCRIPTION
ANTENNA VERTICALE NVIS RACCORCIATA PER RICETRASMETTITORI TATTICI A ONDE CORTE NVIS VERTICAL ANTENNA SHORTWAVE FOR TACTICAL SHORT WAVE TRANSCEIVERS
Il presente trovato concerne un sistema di antenna verticale per ricetrasmissione nella banda delle frequenze comprese tra 2 e 60-80 MHz, adatta all’ impiego su mezzi mobili terrestri o marittimi. Il sistema di antenna à ̈ adatto per comunicazioni a breve e media distanza, utilizzando la propagazione in HF definita in letteratura NVIS, ed à ̈ costituito da un radiatore verticale ripiegato su se stesso e, caratterizzato da uno sviluppo autoportante su di una struttura a revolver in fibra di vetro e acciaio, alta circa 1 metro e che offre una ridottissima resistenza a venti anche molto forti. The present invention relates to a vertical antenna system for transceiving in the frequency band between 2 and 60-80 MHz, suitable for use on land or sea mobile vehicles. The antenna system is suitable for short and medium distance communications, using the HF propagation defined in the NVIS literature, and consists of a vertical radiator folded back on itself and characterized by a self-supporting development on a revolver structure in fiberglass and steel, about 1 meter high and offering very low resistance to even very strong winds.
L’antenna, che ha uno sviluppo lineare, a seconda delle possibili configurazioni compreso tra 6 e 7 metri, à ̈ destinata esclusivamente all’ impiego in abbinamento a ricetrasmettitori tattici a onde corte di tipo sia veicolare che spalleggiabile dotati di dispositivo di accordatore automatico, sia interno che esterno, ed à ̈ destinata principalmente ad impieghi su mezzi mobili campali corazzati e non, così come su unità navali veloci, al fine di consentire con la massima flessibilità di utilizzo, radiocomunicazioni a portata ottica in HF-VHF fino a 80 MHz o in modalità NVIS nelle sole bande delle onde corte. Allo stato odierno la tecnologia offre numerosi sistemi di antenne per telecomunicazioni professionali e militari da bordo di veicoli, ma la maggioranza di queste antenne sono costituite da stili componibili di lunghezza compresa tra 3 e 5-6 metri. Per l’utilizzo a bordo di un veicolo in movimento devono necessariamente essere incurvate sullo stesso e pure legate all estremo, con un cordino isolante, cosicché oscillano fortemente nelle curve o si impigliano nei rami degli alberi. Altri tipi di antenne più compatte utilizzano sistemi di accordo e di adattamento posti nel basamento, realizzati con trasformatori di impedenza su toroidi e avvolgimenti vari che inevitabilmente, per allagarne la banda di funzionamento, riducono efficienza del sistema ed inoltre con difficoltà possono essere accoppiati e cooperare ai complessi sistemi di accordo automatico basato su microprocessore di cui le moderne radio tattiche sono dotate e dei quali le stesse non possono solitamente fare a meno. L’idea a monte del presente trovato à ̈ stata quella di realizzare un dispositivo che fosse leggiero ed affidabile, il più corto possibile, dotato di elevata resistenza ed affidabilità anche nelle più severe condizioni atmosferiche e che fosse senza difficoltà alcuna accettato dall’accordatore automatico di qualunque ricetrasmettitore tattico moderno e presentasse la capacità di operare in modalità NV1S senza la necessità di essere incurvato sul tetto del veicolo, come normalmente à ̈ richiesto alle antenne comunemente adottate dalle Forze Armate. Il presente trovato, ha quindi lo scopo di snellire e compattare i sistemi di antenne HF destinati all’utilizzo su mezzi militari, evitando altresì eccessivi ingombri, specialmente evidenziati dagli operatori a bordo dei battelli d’assalto veloci impiegati dalle Forze Speciali o dalle Unità di soccorso. The antenna, which has a linear development, depending on the possible configurations between 6 and 7 meters, is intended exclusively for use in combination with tactical short-wave transceivers of both vehicular and shoulder type equipped with a tuner device automatic, both internal and external, and is mainly intended for use on armored and non-armored mobile vehicles, as well as on fast naval units, in order to allow with maximum flexibility of use, optical range radio communications in HF-VHF up to at 80 MHz or in NVIS mode in the short wave bands only. Today the technology offers numerous systems of professional and military telecommunication antennas for in-vehicle vehicles, but the majority of these antennas are made up of modular styles between 3 and 5-6 meters in length. For use on board a moving vehicle they must necessarily be bent over it and also tied at the end, with an insulating cord, so that they swing strongly in curves or become entangled in tree branches. Other types of more compact antennas use matching and adaptation systems placed in the base, made with impedance transformers on various toroids and windings which inevitably, by flooding the operating band, reduce the efficiency of the system and also with difficulty can be coupled and cooperate. to the complex microprocessor-based automatic tuning systems that modern tactical radios are equipped with and which they usually cannot do without. The upstream idea of the present invention was that of realizing a device that was light and reliable, as short as possible, with high resistance and reliability even in the most severe weather conditions and that was easily accepted by the automatic tuner of any modern tactical transceiver and had the ability to operate in NV1S mode without the need to be hunched over the roof of the vehicle, as is normally required for antennas commonly adopted by the Armed Forces. The present invention therefore has the purpose of streamlining and compacting the HF antenna systems intended for use on military vehicles, also avoiding excessive bulk, especially highlighted by the operators on board the fast assault boats used by the Special Forces or by the rescue units.
Il trovato può trovare quindi un largo impiego in abbinamento a qualunque ricetrasmettitore HF tattico, con applicazioni che vanno dall’istallazione su veicoli telonati, fuoristrada, mezzi blindati tipo VTLM, mezzi corazzati leggeri e pesanti, oppure a bordo di veloci unità navali, in virtù dell’elevata resistenza alle sollecitazioni quali vibrazioni, vento e altri agenti atmosferici. The invention can therefore be widely used in combination with any tactical HF transceiver, with applications ranging from installation on tarpaulin vehicles, off-road vehicles, armored vehicles type VTLM, light and heavy armored vehicles, or on board fast naval units, in thanks to the high resistance to stresses such as vibrations, wind and other atmospheric agents.
I vantaggi offerti complessivamente dal presente trovato non sono riscontrabili se non in parte e separatamente in alcune realizzazioni industriali molto complesse e costose e che difficilmente presentano una tale flessibilità di utilizzo. The advantages offered as a whole by the present invention cannot be found except partially and separately in some very complex and expensive industrial constructions which hardly have such flexibility of use.
Per la realizzazione pratica della struttura del presente trovato, così come raffigurato nei disegni allegati, à ̈ stato utilizzato uno stilo in acciaio ramato della lunghezza di un metro, dotato di mollone e basamento standardizzato similare a quello usato dalle antenne militari in HF. Un tamburo di materiale isolante con 5 o più fori ciechi perimetrali ed un foro centrale passante attraverso lo stilo, in tutto simile al tamburo di un revolver, agisce da supporto alle bacchette in fibra di vetro, anch’esse della stessa lunghezza dello stilo centrale e che sono inserite nei fori ciechi e fanno altresì da tutore, tramite l’inserimento in una termo guaina, ad un cavetto di acciaio o di altro materiale conduttore che à ̈ collegato elettricamente ad un estremo al tratto superiore del radiatore centrale, e che, nel montaggio, inverte il percorso lungo l’intero sviluppo delle colonnine che circondano l’elemento centrale e che rimane isolato alla fine del percorso. Due dischi, anch’essi di materiale isolante, fanno da supporto centrale e terminale dell’antenna e conferiscono alla stessa una grande robustezza ed una trascurabile resistenza ai venti. Tale configurazione riconducibile intuitivamente a quella di uno stilo ripiegato su se stesso, della lunghezza fisica di 6 o 7 m, proprio a causa della particolare struttura, esalta il diagramma di radiazione dell’antenna verso l’alto, rendendola quindi idonea a comunicazioni su salti quasi verticali nella ionosfera in modalità NVIS. La struttura completa dell’antenna montata à ̈ molto simile, come forma, a quella delle canne rotanti intorno al supporto delle mitragliatrici “Vulcan†. Le caratteristiche tecniche del trovato, secondo i suddetti scopi, sono chiaramente riscontrabili dalle rivendicazioni sotto riportate ed i vantaggi dello stesso risultano evidenti nella precedente descrizione dettagliata, fatta con riferimento al disegno allegato, che ne rappresentano una forma di realizzazione puramente esemplificativa, non limitativa, e in cui: For the practical realization of the structure of the present invention, as shown in the attached drawings, a copper-plated steel stylus of one meter length was used, equipped with a standardized spring and base similar to that used by military HF antennas. A drum of insulating material with 5 or more perimeter blind holes and a central hole passing through the stylus, very similar to the drum of a revolver, acts as a support for the fiberglass rods, also of the same length as the central stylus and which are inserted in the blind holes and also act as a brace, through the insertion in a thermo sheath, to a steel cable or other conductive material which is electrically connected at one end to the upper section of the central radiator, and which, during assembly, reverses the path along the entire development of the columns that surround the central element and which remains isolated at the end of the path. Two discs, also made of insulating material, act as central and terminal support of the antenna and give it great strength and negligible resistance to winds. This configuration, which can be intuitively traced back to that of a stylus folded back on itself, with a physical length of 6 or 7 m, precisely because of the particular structure, enhances the radiation pattern of the antenna towards the top, making it therefore suitable for communications on nearly vertical jumps in the ionosphere in NVIS mode. The complete structure of the mounted antenna is very similar in shape to that of the rotating barrels around the support of the â € œVulcanâ € machine guns. The technical characteristics of the invention, according to the aforementioned purposes, are clearly verifiable from the claims reported below and the advantages thereof are evident in the previous detailed description, made with reference to the attached drawing, which represent a purely exemplary, non-limiting embodiment thereof. and in which:

Sono inoltre evidenti il supporto base a revolver (2) e i supporti strutturali rispettivamente centrale (2.1) e terminale (2.2). Il supporto elastico (3) passa attraverso il basamento isolante e il disco standardizzato NATO (5) e termina nel morsetto di connessione (4) all’accordatore automatico del ricetrasmettitore.
