SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a BS / CS antenna which can be easily disassembled and transported outdoors to be assembled and used on site. is there.

[0004]

Means for Solving the Problems An antenna reflector and L
In a BS / CS antenna consisting of an NB (low noise block) and an arm connecting the reflector and the LNB, a screw mechanism is provided on the reflector, and a screw with a knob is inserted into a hole drilled in the corresponding arm. The arm to which the reflecting mirror and the LNB are attached can be attached and detached without a tool.

The projection is formed on one of the mounting portion or the arm of the reflecting mirror, the hole is formed on the other side for inserting the projection, and the elastic body is inserted into the hole to elastically stop the projection. By inserting the protrusion and the elastic body into the hole and coupling them together, the arm having the reflecting mirror and the LNB attached thereto can be attached and detached without a tool.

The projecting portion and the elastic body are inserted into a hole formed on the other side to be coupled, and a screw is inserted through the hole formed in the inserting portion in a direction substantially perpendicular to the inserting direction.

A carrying handle is attached to the end of the reflecting mirror.

A stationary leg is attached to the end of the reflecting mirror.

When the arm is removed, the leg attached to the end of the reflecting mirror is such that when the lower end of the leg and the lower end of the reflecting mirror are placed horizontally, the center of gravity of the whole of these is approximately the lower end of the leg and the lower end of the reflecting mirror. When the arm is attached, the lower end of the leg and the lower end of the arm are placed substantially horizontally so that the center of gravity of all of them is approximately between the lower end of the leg and the lower end of the reflecting mirror. .

The leg attached to the end of the reflector is such that the elevation angle of the reflector is oriented toward the satellite when the lower end of the leg and the lower end of the arm to which the reflector is attached are placed horizontally.

The leg attached to the end of the reflecting mirror has a variable length relative to the lower end of the reflecting mirror, and when the elevation angle in the satellite direction is different, the elevation angle of the reflecting mirror can be adjusted to face the satellite direction. .

[0012]

The reflecting mirror is provided with a screw mechanism, and a screw with a knob is inserted into a hole drilled in the arm corresponding to the screw mechanism so as to be screwed into and attached to the screw. With the structure, it is possible to configure a detaching mechanism that can be detached without tools.

The projecting portion formed on one of the mounting portion or the arm of the reflecting mirror, the hole portion for inserting the projecting portion formed on the other side, and the elastic body for elastically stopping the projecting portion by inserting the projecting portion into the hole portion. By inserting and coupling the projecting portion together with the elastic body into the hole portion, it is possible to obtain a detaching function in which the reflecting mirror and the arm on which the LNB is attached can be easily disassembled and assembled without using a tool.

When the protrusion and the elastic body are inserted into a hole formed on the other side and coupled, and screwed through a hole formed in the insertion part in a direction substantially perpendicular to the inserting direction, the moving part is moved. Prevents slipping out.

By attaching a handle to the end portion of the reflecting mirror, transportation becomes easy.

By attaching a leg to the end of the reflecting mirror,
The unstable reflector can be placed stably when it is left as it is during transportation or use.

When the arm is removed, the leg attached to the end of the reflecting mirror is such that when the lower end of the leg and the lower end of the reflecting mirror are placed horizontally, the center of gravity of the whole of these is approximately the lower end of the leg and the reflecting mirror. When the arm is attached so that the lower end of the leg and the lower end of the arm are placed substantially horizontally when the arm is attached, the center of gravity of the whole of these is approximately between the lower end of the leg and the lower end of the reflector. By doing so, the reflector and antenna can be stably placed during transportation and installation.

The leg to be attached to the end of the reflecting mirror is installed by setting the lower end of the leg and the lower end of the arm to which the reflecting mirror is attached horizontally so that the elevation angle of the reflecting mirror faces the satellite direction. Sometimes it can be used just by adjusting the azimuth.

The leg attached to the end of the reflecting mirror has a variable length relative to the lower end of the reflecting mirror, and when the elevation angle in the satellite direction is different, the elevation angle of the reflecting mirror can be adjusted to face the satellite direction. This makes it possible to adjust the elevation angle of the antenna even when the elevation angle of the satellite changes due to geographical position movement or when the installation location is not horizontal.
