30107 KM is the name of Russian tubular steel masts for VHF / TV transmission systems, which were erected in several locations in the Soviet Union in the first half of the 1960s . The mast of type 30107 KM usually has a 151 or 182.5 meter high mast body with a wall thickness of 10 to 16 millimeters. It exists both in a version that is guyed in 3 directions and in a version that is guyed in 4 directions.
Its most striking feature, however, which also gives it its characteristic appearance, are the crossbeams arranged in 2 levels, on which there is a walkway with a railing, which leads from the mast body to the outermost guy ropes. These cross members serve to dampen wind-induced vibrations and can also be used to install antennas.
In the area of the former Soviet Union, rope-anchored tubular steel transmission masts were also implemented without these cross members. However, such masts are not particularly unusual, because such structures have also been realized in Germany, the Czech Republic, Slovakia, France, Great Britain, Japan, South Korea, Sweden, Slovenia and Poland.
