PURPOSE:To avoid a radome sheet and an antenna component like a primary radiator from colliding with each other into damage because of wind by fitting a wire member with a tension at the inside of the radome of sheet shape. CONSTITUTION:Two metallic wire members 4 are fixed to the inside of the radome 3 fitted with a tension at the outer circumference of a cylinder 2 fitted to a parabola antenna 1 in crossing so as to provide a tension to the outer circumference of the cylinder 2. Since the bending of the radome sheet is supported, the collision between the antenna component and the radome sheet is prevented. Further, the length of the cylinder 2 is not long, the light weight is attained and the weight given to an iron tower is reduced. |
