Ukrainian T-shaped Radio telescope, second modification

The Ukrainian T-shaped Radio telescope, second modification (official abbreviation UTR-2) is the world's largest radio telescope at decametre wavelengths. It was built in the early 1970s near the village of Grakovo (coord|50|52|N|36|08|E|), 65 km south-east from Kharkov, Ukraine. 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 the collective area of convert|150000|m2|sqft|-5, and the resolution about 40'×40' (12×12 m) at the middle frequency 16.7 MHz. The operating frequency range is 8–40 MHz. The sensitivity is about 10 Jy.

The telescope is a part of the Ukrainian decametric VLBI system URAN, which includes another four radio telescopes of smaller size. The system has bases from 40 to 900 km (25 to 960 mi).
