Description
A kind of high gain all channel turns to parabolic antenna to be used for home television set and receives, and makes the exterior aerial receiving system.
In prior art, it is various in style that home television set receives the chamber, the outside antenna that adopt.Roughly formed with the exterior aerial that the utility model is comparatively approaching by oscillator part, steer motor, all channel antenna amplifier, main control system, support bar.Particularly apart from TV signal emission the relay station area and reception dead angle far away, reception is poor, not fogging clear for this class formation position controlled rotary antenna.In order to solve above-mentioned contradiction, antenna improves gain to increase director dipole, but as director surpass its gain effect and not obvious more than five, but as increase director again, and volume is big, and also inconvenience is installed.Flat for another example back of the body aperture plate reflector antenna, reflected wave can not concentrate on the feed oscillator fully, be very limited so gain, so result of use is still not good.
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of simple in structure, compact, gain height, bandwidth, good in anti-interference performance are provided, and can adapt to the wide band high gain all channel of VHF, UHF and turn to parabolic antenna.
The utility model mainly by oscillator part, amplifier box, main control system, steer motor, turn to remote controller, support bar, holder to be formed.Support bar one end is connected with steer motor transducer part sub-stent, and the other end is fixed on the holder, and the amplifier box is housed in the middle of support bar, and main control system connects the amplifier box, and remote controller is controlled it and turned to.The transducer part branch comprises VHF frequency range oscillator, uhf band oscillator.VHF frequency range oscillator is made up of parabola shaped frame shape feed oscillator (4), parabola shaped frame shape reflection oscillator (2).Parabola shaped frame shape feed oscillator (4) is fixed on the parabola shaped support (8), and parabola shaped frame shape reflection oscillator (2) is fixed on the parabola shaped support (9).The uhf band oscillator is made up of director dipole (7), dual feed oscillator (5), (6), parabola shaped frame shape reflection oscillator (2), reflection oscillator (3).Director dipole (7), dual feed oscillator (5), (6) are fixed on the support (1), and parabola shaped frame shape reflection oscillator (2), reflection oscillator (3) are fixed on the parabola shaped support (9).

The utility model mainly by oscillator part (VHF frequency range oscillator, uhf band oscillator), amplifier box (13), main control system (16), turn to remote controller (17), support bar (14), holder (15) to be formed.Support bar (14) is connected with steer motor (11), oscillator part (VHF frequency range oscillator, uhf band oscillator) support, the other end is fixed on the holder (15), amplifier box (13), main control system (16) connection amplifier box (13) are housed in the middle of the support bar (14), and remote controller (17) is controlled it and is turned to.VHF frequency range oscillator is made up of the parabola shaped frame shape of VHF feed oscillator (4) and the parabola shaped frame shape reflection oscillator of VHF, UHF (2).Wherein the parabola shaped frame shape of VHF feed oscillator (4) is fixed on the parabola shaped support (8), and the parabola shaped frame shape reflection oscillator of VHF, UHF (2) is fixed on the parabola shaped support (9).The uhf band oscillator is made up of UHF director dipole (7), UHF dual feed oscillator (5), (6), the parabola shaped frame shape reflection of VHF, UHF oscillator (2), UHF reflection oscillator (3).Adopt director dipole (7), 5 aluminum pipes, UHF dual feed oscillator (5), (6) to be fixed on the support (1), the parabola shaped frame shape reflection of VHF, UHF oscillator (2), employing UHF reflection oscillator (3), 7 aluminum pipes are separately fixed on the parabola shaped support (9).Support (1) becomes the axial symmetry relation with parabola shaped support (8), (9), and is connected as a single entity, and parabola shaped support (8), (9) are parallel to each other, and the spacing of two supports is 20-30cm.VHF, UHF feed oscillator (4), (5) impedance matching box are installed in respectively in support (10), (12), and cover with plastic cover plate.After the parabola shaped frame shape of VHF feed oscillator (4), UHF dual feed oscillator (5) connect impedance matching box (10), (12) position respectively, through 75
Coaxial cable input all channel antenna amplifier box (13), signal amplifies after indoor main control system (16) inputs in the television set.(18) on the main control system (16) are the definition adjusting knob, and (19) are the wireless receiving window.Known to the parabolic type antenna theory: TV signal passes to and places respectively the reflecting on the oscillator of parabolic path, though be not that homophase arrives, but reflection through the reflection oscillator, whole homophases when arriving focus, in-phase signal can superpose, so when the feed oscillator placed focus, the entire emission device can close the TV signal ripple poly-to the feed oscillator, induced electromotive force increases greatly.In order to realize that the UHF broadband receives, also adopted two-wire oscillator to place the parabolic reflector focus to carry out feed with wide impedance frequency bandwidth characteristics, added the effect of director.So compared with the prior art the utility model has the following advantages: 1, simple in structure, compact, symmetry is good, easily manufactured, gain improves more than 2 times; 2, can realize broadband reception, directivity, strong interference immunity; 3, can carry out two-way according to the different characteristics of VHF, uhf band amplifies, amplifier gain simultaneously again can be convenient adjustable according to the readability of image on indoor host computer, improve the incident intermodulation distortion phenomenon of strong signal effectively, can adapt to different regions resident's the requirement of watching; 4, owing on main control system, also installed radio frequency input socket additional, can insert signals such as video tape recorder, game machine, satellite receiver, cable TV, conversion is convenient, removed from plug labor, can prolong antenna socket life-span of colour TV.5, antenna turns to and adopts the wireless remote control mode, and it is more convenient to include signal.
