We have developed an automatic painting equipment, which paints a cylindrical M.F antenna tower with guy wire as moves up and down. By using this equipment, we can get high efficiency and more short time for painting work. In this system, the moving carrier with spray guns moves up and down along the antenna controlled by the winch placed on the ground. The method of painting is airless spray method with chlorinated rubber paint. It can paint antennas which are 500〜1200mm in diameter and 100〜240m in hight. It can paint whole circumference by using open and shut arm at once. The painted thickness is above 30μm. We have painted the antenna of NHK Kasuga transmitting station in Fukuoka prefecture for the first time.
