Definitions

  • the invention applies to a wide range system for the reception of radiowaves for the FM band and the other wave-frequences , and for the reception of Television image lines on the VHF/UHF channels and/or other signals an aerial can be used for.
  • Radiowaves and TV image lines usually take place through apole on which Rasters and Dipoles in varions shapes and sizes are installed, those must be pointed on the senders that transmit the signals.
  • the Radiowaves and TV image lines are received by an aerial.
  • the aerial only receives the signals well when it is pointed directly to the transmitting-station, and when the aerial is placed in a way that there are no obstacles between the transmitter and the receiver; like Sky-scrapers, Buildingsteel, and/or other constructions that could have an influence on the transmitted signals.
  • Radiowaves and TV image lines depend with today's system very much of other disturbing elements like Planes, Cars, Motorbikes, all kind of Machineries and Climat conditions (atmospherics).
  • the aerialsystems for Radio and TV used so far have some more disadvantages: the immense maintenance need, the space occupancy and the disfigurement.
  • the goal of this invention is to come up whit an aerial system that, without affecting the quality of picture and sound, will avoid the said disadvantages. While constructing an aerial according to the described invention and the drawings enclosed, this goal is reacted.
  • the wide range aerialsystem i constructed from a number of elements made from alumiumbars of round 4mm-that is 0.16 inch in section- to get the sensibility as high as possible and the weight as low as possible.
  • the aerial other materials can be used too, like; Spring- steel, Copper and Brass. All these materials the elements can be made from.
  • the position of the Dipoles assure that these elements will receive transmitted signals, incoming trough the elements E-J-K-L- and M are transmitted to a steeringscreen (draw.XGI).
  • This screen takes care that the pictures (signals) and waves to be recived are free from reflection and other disturbing elements.
  • the signals enter the housing of the elements,where they are connected to 4 element-holders.
  • the signals are transmitted to a series of prints that take care for the following transmitting of the signals.
  • the prints are connected and linked by means of a Pole connectionfilter with 2 tubetrimmers avoiding an overload of signals on the exitsignal of the aerial. Otherwise an overload could enter the receiver and disturb the picture.
  • the prints also can be omitted.
  • the parts are placed in the housing without connection, which is possible because after the assembling the housing will be filled with cast resin or epoxyresin resulting in a definite separation of the elements and avoiding internal failures.
  • FIG. 1 show the side-views of the aerial types A-B-C-D and E, while the drawings II-IV-V-VI and VII show the top-views of the different types.
  • the elements of above mentioned aerials are made- from a certain kind of Duralmin Alumium, where the bars round 4mm are made from .
  • Alumium is chosen because of the different atmos- feric influences. Depending on the circumstances also other materials can be used-some of them are mentioned before.Both thicker and thinner types are useful depending on the demands made and the chosen possibilities.
  • the elements L (see draw. XII L) are placed in an element-holder acc. to drawing IX A. Over or under this holder the elements J and K are installed ( draw. XI J and XII K).
  • connectionfilter draw. XI H
  • print G I draw.X G I
  • tow trimmers are placed on print III (draw. X III).
  • the elements M are placed (draw. XIII M) on the print II and III (draw. X GII and GIII), after that the trimmers are assembled and connected. After assembling and casting a lid (draw. XI I) is placed and the unit is ready now for the setting and control procedures.
  • the aerial After checking the reception of Radiowaves and TV image lines the aerial is ready for installation.
  • the aerial can be installed in many ways. It depends on the situation of the object the aerial has to be placed on.
