30107 KM is the designation of Russian-built guyed tubular masts for FM-/TV-broadcasting, which were built in the first half of the 1960ies at different places in Russia and Ukraine. The 30107 KM-mast has normally a 151 or 182.5 metres high mast body with a wall diametre of 16 – 10 mm and exist as well in a version guyed in 3 directions, but also in a version guyed in 4 directions.
Its most unique feature however, which gives it its characteristic lookout are the crossbars equipped with a gangway with railing, which run in 2 levels from the mast structure to each outmost guy. These crossbars are used for oscillation damping of the structure and are used for the installation of antennas.
However in former Soviet Union also guyed tubular masts for broadcasting without these crossbars were realized. However such masts are not something special as such structures also exist in Germany, Czech, Slovakia, France, United Kingdom, Japan, South Korea, Austria, Sweden, Slovenia and Poland.
