The Murchison Widefield Array (MWA) is a low-frequency radio telescope operating between 80 and 300 MHz. It is located at the Murchison Radio-astronomy Observatory (MRO) in Western Australia, the planned site of the future Square Kilometre Array (SKA) lowband telescope, and is one of four telescopes designated as a Precursor for the SKA.
The MWA consists of 4096 dual-polarisation dipole antennas, arranged as 256 "tiles", each a 4x4 array of dipoles. A complete technical description of the telescope is given in the journal article: The Murchison Widefield Array: The Square Kilometre Array Precursor at Low Radio Frequencies , Tingay, S.J. et al. 2013, PASA, 30, 7.
