The Ukrainian T-shaped Radio telescope, second modification (official abbreviation UTR-2) is the world's largest low-frequency radio telescope at decametre wavelengths. It was built in the early 1970s near the village of Hrakovo (49°38′N 36°56′E / 49.633°N 36.933°E), 15 km west-south-west from Shevchenkove, Ukraine in the time of Soviet Union. The telescope is operated by the Institute of Radio Astronomy of the Ukrainian Academy of Sciences.
The UTR-2 comprises 2040 array elements in two arms: north-south (1800×60 m) and west-east (900×60 m). It has a total area of 150,000 square metres (1,600,000 sq ft), and a resolution of about 40 arcminutes at the middle frequency 16.7 MHz. The operating frequency range is 8–33 MHz. The sensitivity is about 10 Jy.
The telescope is a part of the URAN (Ukrainian Radio Interferometer of NASU) decametric VLBI system, which includes another four significantly smaller low-frequency radio telescopes. That system has bases from 40 to 900 km (25 to 960 mi).
