Abstract

(57) [Summary] (Corrected) [Purpose] To reduce the number of parabola antenna packaging personnel. [Constitution] The reflector of the parabolic antenna is divided. The reflector is vertically halved, and the reflector 101 and the reflector 102 form a pair. It is attached to the reflector by the boss 6 and fixes the reflector and the antenna frame 7. The hinge 4 serves as a fulcrum of rotation when the reflector is bent. In this way, the strength is not weakened because the boss portion and the hinge portion are fixed and divided when attached. Further, the reflecting surface can be arbitrarily divided into 3 divisions, 4 divisions and the like as required.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a parabolic antenna that receives radio waves of satellite broadcasting, and particularly relates to reduction of the number of talents at the time of packaging considering transportation.

[0002]

[Prior Art]

 A conventional technique will be described. Fig. 2 shows a conventional parabolic antenna, 1 is a reflector, which has a parabolic surface and is finished with a metallic surface that reflects radio waves. Fiber-reinforced resin is often used as the material. Reference numeral 2 is a converter that receives the electric waves reflected and focused by the reflector and converts the frequency of the carrier wave to a lower frequency. Since the satellite dish for satellite broadcasting is large as shown in the drawing, it is disassembled into parts for transportation in consideration of transportation. However, there was a problem that the reflector was large and the number of talents for packaging was large. Since the packaging talent is based on the amount that can be loaded in a transport vehicle, the vertical, horizontal, and height dimensions become a problem, and reflectors and the like become unwieldy. Moreover, the weaker the area, the larger the antenna required. Therefore, there was a problem that the packaging talent would be extremely large for packaging in areas with weak radio waves.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a parabolic antenna with a small packaging ability.

[0004]

[Means for Solving the Problems]

 The present invention is a reflector having a parabolic surface that receives radio waves, a converter that receives radio waves from the reflector and converts the frequency to a low frequency, a converter arm that sets the converter to the antenna focus, an elevation angle setting unit, and a pole. A parabolic antenna for receiving satellite broadcasting, which includes an antenna frame composed of a mounting portion, is configured by dividing a reflector plate.

[0005]

With this configuration, it is possible to reduce the total talent by dividing the largest reflecting plate among the components.

【Example】

 The present invention will be described with reference to examples. FIG. 1 shows an embodiment of the present invention 101 is a reflector A. Reference numeral 102 denotes a reflection plate B, and as shown in the divided front view of the reflection plate of FIG. 3, the reflection plate is halved vertically to form a pair of reflection plate A and reflection plate B. A boss 6 is attached to the reflector plate to fix the reflector plate and the antenna frame. A converter 2 receives the electric waves reflected and focused by the reflector and converts the frequency of the carrier wave to a low frequency. Reference numeral 10 is a converter arm for setting the converter at the focal point of the antenna. An antenna frame 7 is composed of an elevation angle setting part 8 and a pole mounting part 11 for fixing a reflector and a converter arm. Reference numeral 9 is a pole, and the parabolic antenna is supported by the pole mounting portion 11, and the root is fixed to the veranda or the attic. 5 is a cable that connects the converter and the antenna terminal of the receiver. 3 is a mounting member for connecting the antenna frame and the reflector. In this embodiment, it is attached to the boss 6 of the reflection plate with a screw to fix the reflection plate and the antenna frame. 4 is a hinge that serves as a fulcrum of rotation when the reflector is bent. In this way, the strength is not weakened due to the fact that it is fixed and divided when it is attached at the boss portion and the hinge portion. The contact surface of the reflection plate AB may be provided with projections and depressions to position it. If there is no problem in size, the strength is increased. Further, by devising the positions of the boss and the hole of the mounting portion, the force can be applied to the contact surface, and the hinge or other reinforcement can be unnecessary. In the embodiment, the reflecting surface is divided into two, but can be divided into three, four, etc., as required. In this case, it is necessary to consider strength and displacement.
