The Yerevan TV Tower is a 311.7 meter high steel lattice tower on Mount Nork in the southeast of Yerevan . It was built from 1974 to 1977 as the successor to a 180 meter high television tower . The television tower is the tallest structure in the country. Its transmission area covers large parts of the Ararat valley . The tower is one of the world's tallest television towers made of steel framework. The operator of the Yerevan television tower is the public television broadcaster ARMTV . The television tower is not open to the public.
The construction of the Yerevan television tower became necessary because the old transmission system could no longer cover the necessary capacities for the growing demand. The old, dismantled transmission system, a simple steel lattice mast construction, was transferred to Gyumri (formerly: Leninakan), where it is still in operation today. In 1977 the number of televisions in Armenia reached half a million, around 100,000 of which were color televisions. So that it was within the Soviet Union , the Union Republic with the second-most distribution. The Yerevan TV Tower began operating on November 29, 1977.
The structural structure of the television tower in Yerevan can be divided into three areas.
The base of the steel lattice tower is a stilt structure made of three pillars. These are shaped by a triangular lattice structure. The pyramidal shape is an equilateral triangle in horizontal section. A single-storey, closed platform with the same cross-section is located at a height of 71 meters. On the roof of this lower tower top are directional antennas housed.
Above this is the middle part, at the end of which there is another, this time two-storey tower cage with a round cross-section at a height of 137 meters. There are further technical facilities for broadcast coverage. The upper tower cage has the shape of an inverted truncated cone and has a diameter of 18 meters at its roof edge. The grid structure continues about 30 meters above it. Above this, the vertical tube construction (4.2 meters in diameter), in which the elevator shaft is hidden, continues as an antenna carrier. This shape was widely used in steel lattice towers in the Soviet Union. The Kiev television tower and the Saint Petersburg television tower , for example, follow this construction principle.
The antenna support tapers (diameter per section: 4 meters, 3 meters, 2.6 meters, 1.72 meters and 0.75 meters) between five maintenance parapets up to the point. The entire steel structure is painted in the warning colors of red and white, in a similar way to the Tokyo Tower and the Tbilisi television tower .
Apart from the necessary air traffic control lights , the tower is illuminated reddish in the evening hours.
