Abstract
Provided is an all-channel outdoor television antenna without turning. A two-loop ring-shaped active oscillator of the all-channel outdoor television antenna without turning is formed by cutting a metallic conductor into a certain length and winding the metallic conductor into the shape of a two-loop ring. The wound two-loop ring shape can be a circular shape, a rectangular shape, a triangle shape, a diamond shape, etc. The all-channel outdoor television antenna without turning does not need a remote control steering electric motor to change the direction of the antenna, and can realize simultaneous broadband reception of the frequency signals of dozens of television programs of a VHF-UHF frequency range from all directions only by using an omnidirectional and all-channel structure design of the antenna itself. Due to the small size and the good wind resistance performance of the all-channel outdoor television antenna without turning, the number of the television program channels received by a television increases, and images are clear and stable. The all-channel outdoor television antenna without turning can be used in urban areas, suburban districts, rural areas, and mountain areas home and abroad, and in various vehicles and vessels in moving for users to receive the omnidirectional and all-channel television (open circuit television) program frequency signals.
Description
Technical field
The utility model relates to a kind of all-channel outdoor television antenna that need not turn to, and can be used to receive the program frequencies signal of looking platform from the VHF band 1-12 channel and the super high band 13-48 channel radio of different directions.
Background technology
At present; Known television antenna mostly need just can be watched TV programme with the direction that the remote control steer motor changes antenna; And in a single day steer motor stop operating and will make antenna can only receive the TV programme signal of some directions, and can't watch the programme signal from from all directions each TV station simultaneously at all, moreover; This steer motor also must be used the 220V ac power supply, and both inconvenience was also dangerous.
The utility model content
The purpose of the utility model provides a kind of all-channel outdoor television antenna that need not turn to; It need not use the remote control steer motor to change the direction of antenna; Only utilize the omni-directional that this antenna self had and the structural design of all-channel; And realize accepting simultaneously for the broadband of overlapping the TV programme frequency signals from VHF-UHF frequency range tens from all directions, because its volume is very little, wind resistance is good; Not only can supply family both domestic and external to use, also can supply to receive on various vehicles and the ship under steam the TV programme signal of comprehensive all-channel.
The utility model solves the technical scheme that its technical problem adopted: its annular active dipole of two circles is with a metallic conductor such as copper pipe, aluminum pipe or iron pipe etc., is cut into certain length, and coiled two circle annulars are processed the annular active dipole of two circles.Two circle annulars of coiled can be shapes such as circle, rectangle, triangle, rhombus.With the distributing point of the annular active dipole two-end-point of two circles and the mid point of the annular active dipole of two circles; With drill bit difference auger shell silk fixing hole, respectively the distributing point of the annular active dipole of two circles and the mid point of annular active dipole are fixed on the insulation joint box with screw again.Be installed in the insulation fixed bin on the annular active dipole of two circles with the screw symmetry, two of the annular active dipole of two circles kept at a certain distance away between enclosing, and be parallel to each other.Plastic three-way pipe fitting and plastic water pipe that a T opaque of connection pipe vertical rod between insulation joint box and insulation fixed bin, the vertical rod of T opaque pipe can select for use running water pipe to use are formed, and play a supportive role.Distributing point in the insulation joint box is connected to the input of the broadband high frequency transmission line impedance converter of this Antenna Design, and the output of broadband high frequency transmission line impedance converter is electrically connected with 75 Europe coaxial-cable feeder and feeder line plug in proper order.75 Europe coaxial-cable feeder are the entrance hole entering from the insulation joint box.The screw fixing hole of 75 Europe coaxial-cable feeder, the lug plate of distributing point are arranged in the insulation joint box.When this antenna is set up in use; Need vertically be fixed on outdoor spacious place to the plastic tube vertical rod of this antenna; The anchor ring horizontal positioned of the two annular active dipoles of circle (1) is used,, inserted the plug of 75 Europe cable feeder lines of this antenna in the antenna jack of television set applicable to receiving from multi-faceted full frequency channel TV program signal; Let television set search for a television frequency signal automatically; Like this, every in the coverage that electromagnetic wave can cover, can receive VL-VHF and a lot of TV programme frequency signal of uhf band from from all directions; And again do not need with the motor watch programs of gyrating.
The beneficial effect of the utility model is, make loop aerial volume-diminished a lot, for the setting up of loop aerial, use convenience is provided; Improved loop aerial receptivity and broadening the working band scope, the programme channel quantity that television set is received increases to some extent, and clear picture, stable; The utility model can be used for both at home and abroad each town and country, suburb, rural area, mountain area, and various vehicles under steam, the user on the ship receive comprehensive all-channel tv (OCTV) program frequencies signal.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is: the basic structure of an embodiment of the utility model and antenna pattern are implemented figure.
The annular active dipole of 1. 2 circles among the figure, 2. insulation joint box, 3. insulation fixed bin, 4. fixed screw, the vertical rod of 5.T opaque pipe, 6.75 Europe coaxial-cable feeder, 7. feeder line plug.
Embodiment
In Fig. 1, with a tubular metal conductor according to the length intercepting that is designed after, coiled annular two circles are processed two circle annular active dipoles (1), the diameter of metallic conductor is 12-20mm.With the distributing point of two circle annular active dipole (1) two-end-points and the mid point of the two annular active dipoles of circle (1); With the drill bit difference auger shell silk fixing hole of diameter 4mm, use fixed screw (4) respectively the distributing point of the two annular active dipoles of circle (1) and the mid point of annular active dipole (1) to be fixed on the insulation joint box (2) again.Insulation joint box (2) is to be made up of terminal box and lid respectively and an entrance hole (not drawing among the figure) arranged.Be installed in insulation fixed bin (3) on two circles annular active dipoles (1) with the screw symmetry, two of the two annular active dipoles of circle (1) kept at a certain distance away between enclosing, and be parallel to each other.Horizontal fixed is installed T opaque pipe vertical rod (5) between insulation joint box (2) and insulation fixed bin (3), and an end of 75 Europe coaxial-cable feeder (6) of a certain-length is penetrated in the entrance hole of insulation joint box (2).Inside at insulation joint box (2) uses the distributing point of the two annular active dipoles of circle (1) fixed screw (4) to be connected with two lug plates respectively; Two lug plates are connected respectively with for the input of the custom-designed broadband high frequency transmission line of this antenna impedance converter again; Be connected with the screen netting twine of 75 Europe coaxial-cable feeder (6) output of this adaptation with heart yearn respectively, connect the feeder line plug (7) in one 75 Europe at the end of 75 Europe coaxial-cable feeder (6).Can also change insulation fixed bin (3) into insulation geometrical clamp, insulation fixed head, more save plastic material.
