A new method for the measurement of on-axis pattern vector and power gain using two identical antennas is described. The antennas must obey reciprocity, but may be otherwise arbitrary; the usual requirements in the conventional 2-antenna gain-measurement method, that the polarisation be known a priori and that the separation be large compared with the Rayleigh distance, are eliminated.
