Therefore, as if the reception of exterior aerial obviously can be improved this disappearance, for remote mountain areas or the not good area of some reception, can reach better reception.And existing exterior aerial mostly is the receive mode 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 align, otherwise reception is not good, and is directly exposed to outer being exposed to the sun and rain because of conventional chamber outside antenna receiving angle is essential, not only easy damage, described aluminum pipe also regular meeting drops, the especially not good even blowing and raining of weather, the reception quality is greatly affected especially.
Summary of the invention
Main purpose of the present utility model is to provide a kind of brill shape antenna receiving unit, and not only receiving angle is broad for it, and stability better, and the reception of high-gain is especially arranged for the UHF signal.
For achieving the above object, the utility model provides a kind of brill shape antenna receiving unit, and it comprises at least:
One shell is container-like, has a tank, and rear end face is formed with a holder, and place, end limit is provided with a connector;
One reflection box is placed in the tank of described shell, and periphery is formed with reflecting plate and centers on, and the bottom punching press has the bent sheet otch, and upwards bending;
One bores the shape antenna, is made up of two quadrangle antenna plate, and upper and lower side is connected on the described bent sheet, and central junction is combined with a waveguide pipe;
One cover plate is with shell seal.
Compared with prior art, the brill shape antenna receiving unit that the utility model provides, not only receiving angle is broad, and stability is better, and the reception of high-gain is especially arranged for the UHF signal.

Embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.
At first, see also shown in Figure 2, the three-dimensional exploded view that decomposes of the present utility model, described antenna 2 includes shell 21, reflection box 22 at least, bores shape antenna 23 and cover plate 24.
Described shell 21 is containers of a hollow, has a tank 210, and place, the back side is provided with a holder 211, and the place, bottom is provided with the connector 212 of a coaxial cable, and is socketed with a waterproof jacket 213.
Described reflection box 22 is inserted in the described tank 210, is formed with reflecting plate 221 all around, and the bottom punching press has bent sheet 222, and bent sheet 222 is upwards bent 90 degree.
Described brill shape antenna 23 utilizes two tetragonal antenna plate 231 and 232 to combine, and both sides offer location hole 2311,2321 respectively, can be for being fixed together with bent sheet 222; Described antenna plate 231,232 central combination ends are connected with a waveguide pipe 233, and utilize cable 234 to be connected to connector 212, establish a cover plate 24 at last and are covered on the shell 21.
