Abstract

The utility model relates to a polydirectional antenna director, which is equipped with a main director and two auxiliary directors. The main director is arranged in the middle of the director; the two auxiliary directors are arranged on the two sides of the main directors; a certain included angle is formed between the two auxiliary directors and the main director; and the two ends of the director are fixed on an outdoor antenna through a big plastic positioning block and a small plastic positioning block respectively. The polydirectional antenna director can enlarge the receiving range of the antenna, keep the high receiving sensitivity, and easily capture radio-frequency signals; and each component is equipped with connected fixing screws, so that the assembly and the use are more convenient, the structure is concise, and the cost is low.

Description

The multi-direction director of a kind of antenna

Technical field

The utility model relates to a kind of sender, particularly relates to the multi-direction director of a kind of antenna.

Background technology

Exterior aerial commonly used at present, for improving the sensitivity of received signal, all can add the director of single direction, antenna has very strong directivity like this, antenna direction must be aimed at television transmitting tower just can have satisfied reception, and the range of receiving of antenna is limited to.Because the influence of atmosphere, building or other obstacles, the radiofrequency signal direction of propagation comes and go, and uses the single direction director to be difficult to catch radiofrequency signal.

Summary of the invention

The purpose of this utility model just provides the multi-direction director of a kind of antenna, can increase the range of receiving of antenna, keeps high receiving sensitivity, easier seizure radiofrequency signal.

For achieving the above object, the utility model adopts following technical scheme:

The multi-direction director of a kind of antenna, comprise: antenna aluminum strip, antenna pole, it is characterized in that: sender is provided with a main director and two secondary directors, main director is arranged on the middle part of director, two secondary directors are arranged on the both sides of main director, become certain included angle between two secondary directors and the main director, the two ends of director are fixed on the exterior aerial with big or small plastics locating piece respectively.

Described main director is made up of nine short aluminum pipes and the strut of drawing money on credit, and nine short aluminum pipes are connected on the strut of drawing money on credit side by side.

Described each secondary director is made up of eight short aluminum pipes and a support bar respectively, and eight short aluminum pipes are connected on the support bar side by side.

The beneficial effects of the utility model: can increase the range of receiving of antenna, keep high receiving sensitivity, easier seizure radiofrequency signal; Each parts is provided with the hold-down screw of connection respectively, assembling, use convenient, simple for structure, at the bottom of the cost.

Specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

Referring to figs. 1 through Fig. 5 as can be seen the utility model comprise: the antenna aluminum strip, antenna pole, described sender is provided with a main director 5 and two

secondary directors

4,12, main director 5 is arranged on the middle part of director, two

secondary directors

4,5 are arranged on the both sides of main director 5, become certain included angle between two secondary directors and the main director, its angle is provided with as the case may be, and the angle operated by rotary motion of main director is between 3 degree are spent to 10, big or small plastics locating piece 1 is used at the two ends of director respectively, 16,6,11 are fixed on the exterior aerial, big plastics locate fast 1,16 are fixed on front end, 6,11 are fixed on the rear end, and this embodiment is screwed.Described main director 5 is made up of nine short aluminum pipes 15 and the strut 14 of drawing money on credit, article nine, lacking aluminum pipe is connected on the strut of drawing money on credit side by side, be that short aluminum pipe is passed hole on the strut of drawing money on credit in this embodiment, be screwed, the strut of drawing money on credit is connected with Module of aerial 8 with reflector net 7,9 through oscillator 10 again.Described each

secondary director

4,12 is made up of eight short aluminum pipes and a support bar 3,13 respectively, and eight short aluminum pipes are connected on the support bar side by side, and the method for attachment of its short aluminum pipe is identical with main director.
