Description
본 고안은 위성안테나의 전파수신위치 조정장치에 관한 것으로, 보다 상세하게는 위성방송텔레비전의 방송수신용 위성안테나에서 소망하는 위성방송전파를 최적으로 수신받기 위해 전파수신부의 수신위치를 용이하게 조정할 수 있도록 하는 위성안테나의 전파수신위치 조정장치에 관한 것이다.The present invention relates to a radio receiving position adjusting device of a satellite antenna, and more particularly, it is possible to easily adjust the reception position of a radio receiving unit in order to optimally receive a desired satellite broadcasting radio wave from a satellite antenna for receiving a satellite broadcasting television. The present invention relates to a radio receiving position adjusting device of a satellite antenna.
주지된 바와 같이, 텔레비전방송국으로부터 전송된 텔레비전방송전파를 인공위성을 중계국으로 하여 지상에 전송시키도록 함에 의해 그 수신적용범위를 보다 더 광범위화한 위성방송방식이 채용되고 있는 바, 이러한 위성방송방식에 따라 전송되는 텔레비전방송전파를 선국하여 재생하기 위한 위성방송텔레비전에서는 해당 인공위성으로부터 전송되는 GHz단위의 위성방송전파에 대해 최적의 수신감도를 갖추고서 수신받기 위한 위성안테나가 설치된다.As is well known, a satellite broadcasting method is adopted in which a wider coverage range is adopted by transmitting a television broadcast signal transmitted from a television broadcasting station to the ground as a relay station. In satellite broadcasting television for reproducing and reproducing television broadcast waves transmitted accordingly, a satellite antenna for receiving reception with optimal reception sensitivity is provided for satellite broadcasting waves transmitted in the GHz unit.
이러한 위성방송텔레비전에 적용된 위성안테나는 도 1에 도시된 바와 같이, 그 설치장소에 따라 길이의 조정이 가능한 폴(2)에 결합된 원형상의 반사판(4)이 설치되고, 그 반사판(4)의 하단으로부터 지지아암(8)에 의해 지지가능하게 연장되어 해당 반사판(4)의 정면과 대면하도록 설치된 전파수신부(6)가 설치된다.As shown in FIG. 1, the satellite antenna applied to the satellite broadcasting television is provided with a circular reflector 4 coupled to a pole 2 whose length can be adjusted according to the installation location thereof. A radio wave receiver 6 is provided which extends so as to be supported by the support arm 8 from the lower end so as to face the front face of the reflecting plate 4.
동 도면에 따르면, 상기 원형상의 반사판(4)이 인공위성을 중계국으로 하여 전송하는 위성방송전파를 유기하여 반사시키게 되면, 그 반사판(4)과 대향하는 상기 전파수신부(6)측에서 반사되는 위성방송전파를 수신받아 LNB측으로 인가할 수 있도록 되어 있다.According to the figure, when the circular reflecting plate 4 induces and reflects the satellite broadcasting electric wave transmitting the satellite to the relay station, the satellite broadcasting reflected by the radio wave receiving unit 6 facing the reflecting plate 4 is reflected. It receives radio waves and can apply them to the LNB side.
하지만, 이러한 위성방송텔레비전에 채용되는 위성안테나에 있어서는 반사판(4)에 대한 전파수신부(6)의 전파수신위치가 그 전파수신부(6)를 지지하는 지지아암(8)의 고정상태에 의해 일정한 간격을 유지하고 있기 때문에, 그 반사판(4)을 통해 반사되는 위성방송전파가 상대적으로 미약한 경우에는 그 전파수신특성이 크게 저하된다는 단점이 있다.However, in the satellite antenna employed in such a satellite broadcasting television, the radio wave reception position of the radio wave receiver 6 with respect to the reflecting plate 4 is fixed by a fixed state of the support arm 8 supporting the radio wave receiver 6. Since the satellite broadcast wave reflected by the reflector 4 is relatively weak, its radio wave reception characteristics are greatly deteriorated.
따라서, 본 고안은 상기한 사정을 감안하여 이루어진 것으로, 위성방송텔레비전용 위성안테나에 채용되는 전파수신부에 대한 반사판과의 수신간격을 조정하여 최적의 전파수신특성이 달성될 수 있도록 하는 위성안테나의 전파수신위치 조정장치를 제공하는데 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and the satellite antenna propagation is achieved by adjusting the reception interval with the reflector for the radio receiver used in the satellite antenna for satellite broadcasting only. An object is to provide a reception position adjusting device.

In a satellite antenna having a receiver, a support arm for supporting the radio wave receiver is rotatably coupled to a lead portion drawn out from a lower end of the reflector by a rotation shaft, and coupled to and interlocked with a motor that is driven forward and reverse.
