Installed in the early 2000, at the radioastronomy station of Nançay, France, the CODALEMA experiment is now a set of various mature apparatus and prototyping instruments.

Within the EXTASIS project, a small set of 7 low frequency antennas has been temporarily installed in some specific locations nearby existing autonomous stations, and three orthogonal dipole antennas have been assembled together to form the tripolar antenna installed nearby the center of the scintillator array. EXTASIS has been dismantled in October 2019, 5 years after its first light, except for the tripolar antenna still is function. The EXTASIS project and its results are described in their dedicated page.
