Simple rock compensating device for antenna mounted on traveling object

Abstract

Abstract PURPOSE:To realize a light weight for the whole of a rock compensating device and facilitate easy control of the natural period of the device, by joining a unified structure of an antenna and a radio machine to a supporter of a traveling object via a rotary junction part and then giving control to the space between the rotational center of the rotary junction part and the centroid of the unified structure. CONSTITUTION:An antenna 3c and a radio machine 13 are fixed relatively in terms of position via an antenna post 4c to form an equivalent pendulum through a unified structure of the antenna and radio machine. A hanging frame 14 has a slender slit 16 at the area of joint to a rotary junction part 15 and in the lengthwise direction of the frame 14. Then a space between the centroid of the unified structure and rotary shafts 7 and 8 each is controlled. After this, a screw 19 is driven. In such way, the rocking of the antenna 3c can be reduced compared with that of a traveling object.
