    • A rotation plate (3) is installed between the control rings (2,2'), positioned at the upper and lower side and controlled by control bolts (1,1'), which perform nought rotation and up-and-down motion. The ropes (9a,9b) engage with fixed pulleys (7,7') and moving pulleys (8,8') installed in an antenna (6) which rotates by a square pillar (4) and a fixing bolt (5). The ropes (9a,9b) are fixed at the inside of the antenna and the ropes (9c,9d) are fixed at the end of moving pulleys (8,8'). The rope (9c) is fixed at outside of the rotation plate through a hole (11) that penetrats the antenna's lower surface. The other rope (9d) is fixed at a twist prevention member (12) installed in the square pillar.
    • 旋转板(3)安装在位于上侧和下侧的控制环(2,2')之间,由控制螺栓(1,1')控制,执行无动作的旋转和上下运动。 绳索(9a,9b)与安装在由方柱(4)和固定螺栓(5)旋转的天线(6)中的固定皮带轮(7,7')和移动滑轮(8,8')啮合。 绳索(9a,9b)固定在天线的内侧,绳索(9c,9d)固定在移动滑轮(8,8')的末端。 绳索(9c)通过穿透天线下表面的孔(11)固定在旋转板的外侧。 另一个绳索(9d)固定在安装在方柱上的防扭转构件(12)上。
