Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a parabolic antenna device for receiving satellite broadcasting, and more particularly to a portable type device.

[Conventional technology]

At present, satellite broadcasting has been put into practical use. However, since this broadcasting radio wave has a high frequency of SHF band (12 GHz band) and is weak, a parabolic antenna or a modification of the parabolic antenna which can obtain high gain in order to receive it. An offset parabolic antenna is required, and a BS converter that converts radio waves received by the antenna into a frequency of 1 GHz band suitable for a BS tuner is also required. Further, a circular / linear polarization converter for converting an input radio wave from a circular polarization to a linear polarization is also required so as to match the input structure (square waveguide) of this BS converter.

Therefore, this type of antenna device is integrated with a primary radiator (feedphone) that centrally inputs radio waves, the above-mentioned circular / linear polarization converter, and a reception conversion unit such as a BS converter. Received radio waves are supplied to the BS tuner by a coaxial cable.

[Problems to be solved by the invention]

However, such a parabolic antenna device is fixedly attached to the ground by a foundation work, which requires special work.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a parabolic antenna device that is portable and can be easily installed indoors.

[Means for solving problems]

To this end, the present invention provides a parabolic antenna device composed of a reflector and a reception conversion unit located at the focal point of the reflector, using a pipe frame bent in a stand shape as a support member,
The reflecting mirror is supported at one end of the pipe frame and the reception conversion unit is supported at the other end of the pipe frame, the center of the pipe frame serves as a stand, and a portion of the stand extends downward from the stand. It is configured by providing an adjusting leg for adjusting the elevation angle, which is capable of adjusting the protruding length that protrudes.

〔Example〕

Embodiments of the present invention will be described below. FIG. 1 is a diagram showing an antenna device of the embodiment. The satellite dish receiving parabolic antenna device A according to the present embodiment includes a reflector 1,
It is composed of a pipe frame 3 and a converter 2 which is located at the focal point of the reflecting mirror 1 and receives a radio wave reflected by the reflecting mirror 1 to convert it into a frequency signal of a lower 1 GHz band.

This pipe frame 3 is one bent in the shape of a stand, and the portion 31 bent in the shape of a hairpin is the reception conversion unit 2.
A rubber leg 4 is attached to the front side of a stand portion 32 which is bent in the opposite direction and extends so as to expand at a slight angle, and an adjusting leg 5 is attached to the rear side thereof, and is further bent in the direction opposite to the folding direction. The end 33 supports the back surface of the reflecting mirror 1.

The rubber leg 4 is fitted in the frame 3, and the adjusting leg 5 is composed of a bolt 51 inserted into the frame 3 and nuts 52 and 53 screwed on the bolt 51 above and below.

Therefore, the antenna device A of this embodiment can be placed directly on the floor 6 in the room, and the elevation angle at this time is the nut 5 of the adjusting leg 5.
It is possible to adjust the distance from the frame 3 of the bolt 51 to the floor 6 by loosening the screws 2, 53 and set the angle in the east-west direction by moving the antenna device A itself.

[Effect of device]

From the above, the parabolic antenna device of the present invention uses a pipe frame bent into a stand shape as a supporting material, so that the whole is lightweight, and it can be easily installed in any place in the room and easily moved from there. Become. Moreover, the elevation angle can be easily adjusted by adjusting the projection length of the adjustment compression, and the azimuth angle can be easily adjusted by the orientation of the entire apparatus.
