Abstract
The utility model relates to a magnetic bar type full-frequency channel antenna for televisions, which is composed of a vibrator 1, an output capacitor 6, a feed line 7, etc. The utility model is characterized in that the vibrator 1 is composed of 2-5 vibrator units 10, each vibrator unit is composed of two parallel metal rods 11, magnetic media 2 are filled between the two metal rods, an insulating layer 3 is arranged between the metal rod and the magnetic media 2, and the vibrator units 10 are placed side by side and are connected in parallel by the capacitor 6 and the feed line 7. The utility model can receive all channel signals, and the gain of each channel signal is higher and more uniform. The utility model has the advantages of low cost and small volume, and the utility model can be used as an indoor antenna or an outdoor antenna.
Description
The utility model belongs to radio receiving antenna, particularly television receiving antenna.
Along with the generally use of television set, the TV station in a lot of areas is increased to the more broadcasting of multiple programs from the 1-2 programs, and the frequency distribution of these programs is on VHF and uhf band.For adapting to the television antenna that multiple programs receives, its kind and form are also more and more.Wherein, with the reception antenna of two half-wave dipoles, be a kind of comparatively simple multi-band antenna, the antenna of other type in this class antenna and the prior art, the following shortcoming of ubiquity:
1, in same frequency range, the gain that receives full channel tv signal can not take into account.
2, numerous antenna is to go to determine the size of antenna with the centre wavelength of the channel that receives, thereby occurs receiving big than the spatial volume of the antenna of low channel, and the metal material consumption is many, the cost height.
3, antenna set up, use difficult, also be difficult for maintenance and safeguard.
In order to overcome above-mentioned shortcoming, the ad hoc the utility model of having counted.
The purpose of the utility model design is: design a kind of antenna that can receive all channels, this antenna not only volume is little, in light weight, easy to manufacture, and is easy to use low with cost.
The purpose of this utility model is achieved in that
A kind of magnetic bar type all-channel television antenna is made up of oscillator 1, output terminal capacitor 6, feeder line 7 etc.It is characterized in that oscillator 1 is made up of two to five oscillator unit 10, each oscillator unit 10 is made of two parallel metal bars 11, fill magnetic medium (2) between two metal bars, the magnetic medium of filling is between two metal bars, so magnetizing mediums is bar-shaped, the cross section of bar magnet can be square, polygon, circle or other shapes, be preferably circular or oval, one insulating barrier (3) is arranged between metal bar 11 and the magnetizing mediums (2), insulation processing can be made in metal bar surface or bar magnet surface, also can simultaneously insulation processing be all made on the surface of metal bar and bar magnet, each oscillator unit 10 is placed side by side and by capacitor 6 and feeder line 7 parallel connections.
Technique scheme has following advantage:
1, can receive the signal of all channels, and have more even higher gain.
2,, use even in the house of reinforced concrete frame structure, still can make domestic aerial as long as reach certain field intensity in the space that receives.
3, antenna oscillator length does not depend on centre wavelength, and wireless spatial volume is little.Now an embodiment of the present utility model and accompanying drawing are described as follows together:
Fig. 1 is the structural representation of embodiment.
Magnetic medium in the middle of the magnetic bar type all-channel television antenna as shown in the figure, oscillator 1 is general radio with bar magnet 2, and is insulating barrier in the sticking one deck insulation in bar magnet surface book film 3.Present embodiment also is provided with a baffle box 4, and antenna is respectively organized oscillator 1 shielding, and baffle box 4 be a rectangle, and a side 41 parallel with each group oscillator 1 is unlimited, makes for sheet metal for all the other five.The fixing location-plate up and down 51,52 by insulation of each oscillator unit 10 is realized, has the fixing hole 53 identical with oscillator 1 cross section on the location-plate.About in the of 1 1/10 place for the oscillator that lays respectively at of location-plate 51,52 up and down, is pasted with sheet metal 54 at following location-plate 51 on output one side.Be protection baffle box 4, there is a plastic casing 42 baffle box 4 outsides, and the sheet metal of baffle box 4 is pasted on the shell 42, has feeder line 7 fairleads 43 on the lower panel.The length of oscillator metal bar 11 is 55-200mm, and oscillator 1 is made up of two oscillator unit 10.
