It has been observed in the far radiating zone that at a certain receiver antenna position and orientation the transit time of the arriving pulse‐modulated microwaves in open space was constant regardless of the distance between the receiver and the transmitter. The apparent phase velocity exceeded the intrinsic velocity. Calibration techniques employed and repeated time‐domain measurements done at different frequencies and distances confirmed this phenomenon.
