The Indosiar Television Tower is a 395 m (1,296 ft) guyed mast used for FM- and TV-broadcasting in West Jakarta, Indonesia, completed in 2006. It is currently the tallest structure in Indonesia. It consists of a 375 metre tall lattice structure with a side length of 6.3 m (20.7 ft), which carries on its top a 20 m (65.6 ft) high TV-broadcasting antenna. The upper parts of the mast are guyed to a 120 m (390 ft) triangular lattice steel structure with a side length of 56 m (183.7 ft), which was built around the mast. This special design, which gives the tower a unique shape, was chosen because of the lack of space available on the site.
