The Ukrainian T -shaped Radio telescope, second modification ( official abbreviation UTR -2) is the largest short-wave radio telescope in the world.

The plant is located about 60 km southeast of Kharkiv, near the village Rakovo (49 ° 38 ' 17 "N, 36 ° 56 ' 10" O49.63805555555636.936111111111Koordinaten: 49 ° 38 ' 17 "N, 36 ° 56 ' 10 " O ), 40 km north- west of Belgorod, Russia. The pilot plant was added in 1970, since 1972, run regular scientific measurements.

This telescope is operated by the Institute of Radio Astronomy of the Ukrainian Academy of Sciences.

UTR - 2 consists of a box with 2040 individual antennas, which are divided into two branches: the north-south arm (1800 m × 60 m) and the east-west arm (900 m × 60 m). It has a measurement area of ​​150,000 m².

The individual antennae are dipole, comprising two wire cylinders of each 4 m long and 1,80 m in diameter. Is measured in a frequency range of 8-40 MHz, at the center frequency of 16.7 MHz, the resolution is approximately 40 '× 40'. The plant has a sensitivity of 10 Jy.

The telescope is also part of the Ukrainian VLBI system URANIUM, which measures the decameter range and includes four other smaller radio telescopes. The base lengths vary from 40 km to 900 km.
