Abstract
The utility model discloses an all-direction all-band television receiving antenna, which comprises a metallic barrel-shaped isolator. Metallic annular induction lines with effective amounts are sheathed at the outside of the metallic barrel-shaped isolator, and have the same diameter or different diameter. Core wires of coaxial feeders are connected with the annular induction wires. A shielding layer is connected with the isolator. The utility model is arranged on an outdoor appropriate place, the direction of the all-direction all-band television receiving antenna is not adjusted, and then all-direction all-band horizontally polarized broadcasting television signals can be received. The utility model has the advantages of simple structure and stable received signals.
Description
The utility model relates to a kind of television receiving antenna, particularly a kind of omnidirectional all band television receiving antenna.
Along with human material and cultural life level's raising, TV has been popularized for huge numbers of families.Yet,,, still adopt the exterior aerial received television signal because cable TV is not installed by most families in vast rural area.Exterior aerial of the prior art can't realize that omnidirectional all band TV signal receives, therefore, in fact in vast rural area because antenna technology falls behind, also restricted popularizing of TV.
The purpose of this utility model is to provide a kind of omnidirectional all band television receiving antenna, and it can realize omnidirectional's all band of TV signal is received as a kind of exterior aerial.
The utility model is realized as follows.Comprise a tubular isolator in the structure of this antenna, it is made with metal material, be set with the same footpath of effective quantity or the metal ring line of induction of reducing layered arrangement in the isolator outside, leave between the isolator and the line of induction at interval, the heart yearn of coaxial feeder links to each other with the metal ring line of induction, and the screen of coaxial feeder is connected with isolator.
Television receiving antenna of the present utility model is erected at outdoor correct position, generally need not to adjust the broadcast television signal that direction can receive omnidirectional's all band horizontal polarization, and signal receives stable, has also improved the television reception quality simultaneously.
What accompanying drawing 1 provided is structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further.
With reference to accompanying drawing 1, the isolator 1 of this antenna is the tubular that is surrounded by sheet metal or wire netting, this tube can have opening, also can not establish opening, the toroidal inductive line made from metal material 2 and 3 at the outside of isolator 1 suit, two rings can Different Diameter, the toroidal inductive line can be a circle or a multi-turn, also can be one or more layers, and the toroidal inductive line also can have opening or not establish opening, leave between isolator 1 and the line of induction 2 and 3 at interval, gap size can be by the different needs setting.Between the line of induction and the line of induction, can interconnect arbitrarily with conductor according to different needs between the line of induction and the isolator.
The toroidal inductive line can be a wire, also can be sheet.
The heart yearn of coaxial feeder 4 links to each other with the line of induction, and the screen of coaxial feeder links to each other with isolator.
The isolator and the line of induction are fixed on the skeleton of being made by insulating material, are convenient to assembling.
