Title:
BALANCE WEIGHT MECHANISM FOR MOVING ANTENNA
Document Type and Number:
Japanese Patent JPH01274504
Kind Code:
A
Abstract:
PURPOSE: To avoid the total weight of a moving antenna from getting too much by using a spring.
CONSTITUTION: The opposite side of a support 2 of a parabolic antenna 1 supported and movable by a bearing 4 of a base plate 5 is coupled with the bearing 4 via a spring 3 and the spring 3 acts like a balance weight. Since it is not required to add a weight close to the weight of antenna, the total weight of the moving antenna is not increased.
