An efficient NF–FF transformation with spherical spiral scanning tailored for elongated antennas is here developed. To this end, such a kind of antennas is no longer considered as enclosed in a sphere, but in a prolate ellipsoid, thus allowing one to remarkably reduce the number of needed data. Moreover, such a source modelling remains quite general and con- tains the spherical one as particular case. Some numerical tests, assessing the accuracy of the technique and its stability with respect to random errors affecting the data, are reported.
