RECEIVING ANTENNA SET FOR SATELLITE BROADCASTING |
摘要 |
PURPOSE:To facilitate indoor installation adjustment and to receive both clockwise and counterclockwise polarized waves by one set by coupling a panel which serves as both a reflector for reflecting a radio wave from a satellite to a plane antenna and a support member for making the antenna part independent rotatably with an end part of the antenna part. CONSTITUTION:The box-shaped antenna part 4 is formed of the flat plate type plane antenna 2 which receives the radio wave from the satellite 1 and a converter 3 which converts the output of this plane antenna 2 to a proper frequency. Then the panel 5 which serves as both the reflector for reflecting the radio wave from the satellite 1 to the plane antenna 2 and the support member for making the antenna part 4 independent is coupled rotatably with the end part of the antenna part. Consequently, the panel 5 which is coupled rotatably is used as the support member to make the antenna part 4 stand by itself at a desired indoor or outdoor position, and then the plane antenna 2 of the antenna part 4 receives the clockwise and counterclockwise polarized waves of the radio wave from the satellite 1.
