description
The television tower, designed as a steel lattice tower, tapers towards the top, unlike most of its counterparts, not linear or concave, but convex. The half-timbered construction is based on three main pillars, each composed of two massive steel tubes. These support a vertically running core structure that is used as a duct. The frame construction is covered in white lacquer.
The system is cabled via a horizontal supply shaft on the ground that is connected to a base house. This belongs to the Seto Digital Research Park Center broadcasting station .
