PURPOSE:The dielectric thin film containing no rotary axis at the center area is rotated by compressed air in order to clear away the attachment such as waterdrop, stains, etc. through centrifugal force. Thus, the dielectric film surface is always kept clean, at the same time maintaining the antenna in the best state at all times. |
