English: The Ukrainian radio telescope UTR-2 - the world's largest low-frequency radio telescope at decametre wavelengths. It consists of a T-shaped array of 2040 broadband cage dipole antenna elements. A few of the elements are seen here. Each dumbbell shaped element is 1.8 m in diameter and 8 m long, made of galvanized steel wire, mounted 3.5 m above the ground, with a balun to connect it to the transmission line These large cylindrical elements allow the antenna to receive a wide bandwidth of frequencies from 8 to 33 MHz. |
