I was concerned about a similar problem with a 4-bay UHF bowtie antenna. As the wavefront reaches the antenna, current is induced in the elements of all four bays at the same time. However, the current from Bay No.1 has to travel along a half wave section of the phasing line before it reaches Bay No. 2. The current changes direction every half wavelength, so the phasing line is reversed to compensate for that, but isn't the current arriving too late?
The answer to the dilemma is that the currents rise, fall, and change direction in all the elements at the same time, which is another way of saying that they are in phase.
