Abstract
The utility model relates to an all-channel TV antenna. Two sets of U band dipoles are arranged in front of a set of X-shaped dipoles; one set of the U band dipoles are isosceles triangle metal plate dipoles which are arranged axisymmetrically; the other set of the U band dipoles are metal tube dipoles which are arranged axisymmetrically; the two sets of the U band dipoles which are parallel and close to each other are arranged on a mounting seat of the U band dipoles, and a set of U band reinforcing dipoles which are connecting-rod-typed are arranged along an axial direction between the X-shaped dipole and the two sets of U band dipoles. The utility model has the advantages of high gain and less loss.
Description
The utility model relates to the knockdown full channel tv receiving antenna of a kind of many oscillators.
China's television broadcasting frequency occupied channel has 1～58 channel at present, seek out reception preferably, the television receiving antenna that just must use adapts with it, except common antenna, most user uses the reception antenna of single oscillator, and the antenna of single oscillator, in any case also can't adapt to so many channel.X-shaped all channel antenna commonly used is only applicable to the 1-12 channel, be actually a kind of VHF wave band, be called for short the V-band antenna, therefore, need a kind of UHF wave band that both adapted to of design, be called for short the all-channel television antenna that U wave band (13～58 channel) adapts to V-band (1～12 channel) again.
The purpose of this utility model just provides a kind of all-channel television antenna.
The purpose of this utility model is achieved in that one group of V-band X-shaped oscillator front two groups of U wave band oscillators is set again, one group of oscillator is the isosceles triangle metallic plate oscillator that axial symmetry is installed, another group oscillator is the metal tube oscillator that axial symmetry is installed, two groups of parallel reclining of oscillator are installed on the U wave band oscillator mount pad, between X-shaped oscillator and two groups of U wave band oscillators, also have one group to connect rod-type U wave band enhancing oscillator vertically, four groups of oscillators are connected in parallel.Wherein the X-shaped oscillator can receive the 1-12 channel signals, and two groups of U wave band oscillators can receive 13～58 channel signals, connects rod-type U wave band and strengthens oscillator, can strengthen the U band signal, also can strengthen the V-band signal.The impedance design of every group of oscillator is 300 Europe, then four groups and to connect the back impedance be 75 Europe, links with 75 Europe feeder lines and can introduce television receiver.
The utility model has been compared following advantage with existing simple oscialltor antenna:
Owing to increased U wave band antenna oscillator, not only can improve the gain of U band signal, and can improve the V-band signal gain, after tested, in the plains region, apart from launching tower 50 kilometer range, the 1-58 channel all can obtain 57-65 decibel signal.
Owing to adopt four group of 300 Europe oscillator requirement that realizes 75 Europe coupling in parallel, thereby reduced the loss of impedance transformation.
Further describe embodiment of the present utility model below in conjunction with accompanying drawing.

Fig. 3, winding diagram (Figure 1A is to view)
Referring to Fig. 1, an example of the present utility model, an X-shaped oscillator 1 is arranged, be fixed on the plastic mounting seat 3 by four aluminum pipes, mount pad is provided with four fixedly fixed sleevings 2 of aluminum pipe, in X-shaped oscillator front, two groups of U wave band oscillators are arranged, one group of oscillator is the isosceles triangle metallic plate oscillator 7 that axial symmetry is installed, parallel the abutting in together of 8, two groups of oscillators of aluminium-alloy pipe oscillator that another group is installed for axial symmetry is installed on the U wave band oscillator mount pad 6, metallic plate oscillator and mount pad are screwed, and the metal tube oscillator is inserted on the plug tenon 10 of mount pad.Between X-shaped oscillator and two groups of U wave band oscillators, be provided with one group vertically and connect rod-type U wave band enhancing oscillator 4, this oscillator is two parallel Metallic rod, one end is fixed in the location hole 9 of U wave band mount pad, and electrically connect with U wave band oscillator, the other end is fixed in the X-shaped oscillator mount pad location hole 5, and electrically connects with the X-shaped oscillator.First effect of this oscillator is to make U wave band oscillator and X-shaped oscillator separate 90 millimeters distances, and second effect is that the gain of U wave band and X-shaped oscillator is improved, and the 3rd effect is that four groups of oscillators are connected in parallel, and realizes 75 Europe impedance matchings.U wave band oscillator and X-shaped oscillator axial distance are 90 millimeters, and the two Metallic rod spacings that connect rod-type U wave band enhancing oscillator are 35 millimeters.
For the ease of wiring and outdoor mounted,, also be provided with metal connecting sheet 11, ply-yarn drill 13 and snap ring 12 is installed at the back side of X type oscillator mount pad.External feeder line 14 electrically connects with brace.
