The Indosiar Television Tower is a 395 m (1,296 ft)^[1] 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. Broadcasting is run by the national television network, SCTV, Indosiar, Moji, and Mentari TV, all of which is owned by Surya Citra Media, a part of Elang Mahkota Teknologi.
