DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a satellite antenna apparatus for receiving signals from a broadcasting satellite or a communication satellite in a geosynchronous orbit, and more particularly to a satellite antenna apparatus which can be easily installed on a veranda.

[0002]

2. Description of the Related Art In recent years, the number of homes equipped with a receiving system for BS has increased due to the full-scale start of satellite broadcasting by a broadcasting satellite (hereinafter referred to as BS). This BS
The receiving system includes a BS antenna and a BS tuner. And the antenna for BS,
In general, a reflector having a parabolic surface, a feed horn for taking in a signal of a radio wave reflected and focused on the reflector, and a frequency of a radio wave taken into the feed horn are input to the BS tuner. LNB (hereinafter, referred to as LNB) which outputs the signal at a frequency reduced to a frequency, and is of a type called a parabolic reflector (parabola).

Conventionally, since the BS antenna has a large elevation angle with the satellite, it is often mounted on a handrail column of a veranda which is relatively easy to install unless a building adjacent to the satellite is too high. Many. When the BS antenna is mounted on the support, the BS antenna is mounted on a round pole in advance so that the elevation angle can be changed.
The pole is attached to the support of the handrail of the veranda by a mounting bracket. Next, the elevation angle of the BS antenna is adjusted and the direction is adjusted by rotating the pole.

[0004]

By the way, the shape of the handrail support of the veranda includes a cylindrical shape, a rectangular tube shape, a thin plate shape, and the like. The mounting bracket depends on the shape and thickness of the support. , Different ones are prepared. Therefore,
When mounting the BS antenna, it is necessary to check the shape and thickness of the support in advance, and then prepare the mounting bracket, which makes the mounting operation of the BS antenna complicated. In particular, in the case where the BS broadcast viewer performs the installation work of the antenna by himself, when purchasing the antenna, he often purchased the wrong mounting bracket and had to replace the mounting bracket in many cases. .

In the case where the mounting bracket is attached to the handrail, the handrail may be cylindrical or rectangular in shape, and has a different thickness. The mounting bracket must be selected according to the shape of the slide. Also, when making fine adjustments to the direction of the antenna, it is necessary to check the TV screen using the antenna level display function built into the BS tuner. One person had to adjust the direction of the antenna, which was a tedious task.

When the rotating shaft 2 is rotated, the fixing plate 4d and the supporting piece 1d of the antenna unit 1 are fixed so that the optimal direction for receiving the radio wave of the reflecting plate 1a can move along the stationary orbit. Further, the fine adjustment Yosu accuracy, it is possible to change the elevation angle depending on the adjustment bolt 4 l.

Then, the direction of the antenna unit 1 is matched with the direction of the CS or BS to be received by the remote rotation controller of the rotation device 3 based on the antenna level indication displayed on the screen of the television.

As described above, according to the satellite antenna apparatus A of the present embodiment, it is possible to mount the handrails B having various shapes according to the handrails B and the columns C of the handrails B. Correspondingly, there is no need to change the mounting bracket as in the conventional example, and the antenna section 1 can be easily mounted on the handrail B of the veranda.

Further, the fine adjustment of the antenna unit 1 after the mounting can be performed by the rotating device 3 which can be remotely controlled, and the fine adjustment of the direction of the antenna unit 1 can be easily performed while watching the screen of the television. it can.
