Description

A kind of exterior aerial receiving system

Technical field

The utility model relates to a kind of antenna receiving unit, relate in particular to a kind of structural improvement of exterior aerial receiving system, it mainly has a reflection box in the enclosure, be positioned at described reflection box and be connected with a dash receiver, and be connected with the antenna waveguide pipe, by the reflecting plate around the reflection box, not only make receiving angle broad, and stability is better, and the reception of high-gain is especially arranged for the UHF signal.

Background technology

Antenna assembly is the indispensable product of TV reception, except viewing and admiring cable TV (CATV), if received signal is watched program voluntarily, all must use antenna, and antenna assembly is divided into domestic aerial and exterior aerial, traditional domestic aerial structure, as shown in Figure 1, mainly have a circuit board 1, centre is a line areas 11, and both sides are provided with dash receiver 111, and the circuit of described dash receiver 111 and described line areas 11 is printed on the described circuit board 1 simultaneously, can receive the signal of UHF by described dash receiver 111, connect copper bars 112 as for the signal of VHF by line areas 11 and receive, whole device is very simple.So look into; though described existing circuit board 1 size is not little; but actual line areas 11 has only a central fritter; occupied most space because be printed on the dash receiver 111 of both sides simultaneously; promptly increased many manufacturing costs virtually, because printed circuit board (PCB) all is to come accounting price with size, and Indoor antenna device is subject to building framework or other factors; there is the reception dead angle in regular meeting, to such an extent as to reception is not good or be interfered etc.

As if therefore, the reception of exterior aerial obviously can be improved this shortcoming, for remote mountain areas or the not good area of some reception, can reach better reception.And existing exterior aerial mostly is the receiving system of fishbone, utilize in a skeleton that aluminum pipe is parallel to be inserted in the skeleton, establish a line box then in the lower end, be connected in described reception antenna, and utilize cable to connect backguy the line box to television set, reach and signal can be received to TV for watching, and described antenna can be for the fixture that is fixed in bamboo pole or eminence.So because of the essential alignment of conventional chamber outside antenna receiving angle, reception is not good, and is directly exposed to outer being exposed to the sun and rain, not only easy damage, and described aluminum pipe also regular meeting drops, the especially not good even blowing and raining of weather, the reception quality is greatly affected especially.

The creator specializes in the development and Design work in electronic product, because of required in view of not satisfying in the use of conventional chamber outside antenna, so do one's utmost to think hard solution, and the specialty that relies on itself reaches working experience for many years, finally after going through test for several times, revise and improving, initiate out the utility model.

Summary of the invention

Main purpose of the present utility model is to provide a kind of exterior aerial receiving system, and its receiving angle is broad and stability is preferable.

In order to achieve the above object, the utility model provides a kind of exterior aerial receiving system, and it mainly is made up of shell, reflection box, dash receiver and capping.Described shell is the container-like of hollow, and bottom place is provided with a holder, can be for being incorporated on bamboo pole or other fixtures, and at the place, end limit of shell and be connected with the connector of coaxial cable.Be positioned at enclosure and be formed with a reflection box, formed by the reflecting plate bending around the described reflection box.And above the reflection box, be provided with a supporting seat, can be for dash receiver being fixed in the reflection box.Be connected with an antenna guide wave device as for described dash receiver, and the connector that utilizes coaxial cable to be connected to the shell end limit uses for being connected.In addition the top place be provided with one with the capping of enclosure closed, have water-proof function and avoid rainwater to infiltrate enclosure, guarantee the stable of received signal, and have more progressive and practical effect than the conventional chamber outside antenna.

Compared with prior art, exterior aerial receiving system described in the utility model, its receiving angle is broad and stability is preferable.
