The first three terms of the asymptotic decomposition of the transfer ration between two antennas with arbitrary directional diagrams and polarization types are obtained. The formulas for the distance that can be used to measure primary and lateral radiation with the given inaccuracy are derived.

The current is found as a series that converges to L2(s) surface norm. The conditions of realizability of the diagram are examined, and methods of determining current using the given unrealizable diagram are specified.
