Abstract	This work concerns the experimental validation of a new near-field - far-field transformation technique with helicoidal scanning tailored for elongated antennas. Such a transformation is based on the theoretical results relevant to the nonredundant sampling representations of the electromagnetic fields and uses a proper source modelling particularly suitable to deal with this kind of antennas. By employing such an effective modelling, instead of the spherical one, it is possible to remarkably reduce the error related to the truncation of the scanning zone, since measurement cylinders with a diameter smaller than the source height can be used. The validity of this innovative scanning technique is assessed by comparing the reconstructions obtained from the data directly measured on the classical cylindrical grid with those recovered from nonredundant measurements on the helix.
