Abstract

PURPOSE:To attain the easy and precise installation of a satellite broadcast transmission/reception antenna in a short time regardless of its installing place by securing the adjustment of the antenna together with the confirmation of an azimuth and a wave angle. CONSTITUTION:An antenna part 14 is assembled and turned into the direction where two marks of an azimuth gage 16 are coincident with each other. At the same time, the gage 16 is always kept horizontal and turned into a fixed direction by the earth magnetism. When both marks are coincident with each other, a wave angle and an azimuth are set at 38 and 51 respective. Based on this direction, the part 14 is swung by a lever 21 by several degrees of the wave angle and the azimuth. Then the lever 21 is released at a point where the pointer of a level meter 17 has the maximum swing. Thus the part 14 is fixed to a main body 13. In such a constitution, an operator can adjust the part 14 while confirming both the wave angle and the azimuth. Thus a satellite broadcast transmission/reception antenna can be easily and precisely installed regardless of its installing place.

As shown in FIG. 2, the antenna adjustment mechanism section 1
The reference numeral 5 is removably attached to the main body 13 by the attachment tool 20. The antenna adjustment unit 15 is attached to the attachment 20 so as to be angularly displaceable by, for example, a ball pipe joint (not shown), and has a built-in lock mechanism that can be locked at a desired displacement position.

As a result, when the user holds and pulls the gun grip type lever 21, the antenna adjusting mechanism 15 can be freely moved with respect to the main body 13 in both the azimuth direction and the elevation angle direction. ing. In addition, by returning the lever 21, the antenna adjustment mechanism 15
Can be fixed to the main body 13.

At the top of the antenna adjustment mechanism section 15, BS
The antenna unit 14 is fixed. BS antenna unit 14
An azimuth meter 16 as an indicator is attached to the back side of the upper part of the, and a level meter 17 is attached to the back side of the middle part of the BS antenna section 14. This level meter 17
As will be described later, it is a meter that displays a level relating to the reception state of satellite broadcast radio waves.

FIG. 3 shows a cross section of the compass 16.
The azimuth meter 16 indicates an elevation angle and an azimuth angle. The structure will be described. The sphere 18 that is the main body of the compass 16 is fixed to the BS antenna unit 14 by a mounting member 19. The sphere 18 is formed of a transparent material, and the inside thereof is formed hollow, and accommodates kerosene, for example. A display unit 30 as shown is accommodated in the sphere 18. The display unit 30 is provided with a magnet 31 and can rotate around a ball 32.

The display unit 30 has a structure that sinks in kerosene, the ball 32 always moves to the lowermost part of the sphere 18, the display unit 30 always keeps horizontal, and the magnet 31 moves in a certain direction by the earth's magnetism. It is structured to face.
