Ron The short answer is simple. Beverage antenna is really a transmission line with all proprieties of a transmission line, in one side is terminated by a load and on the other side by a transformer. The difference in speed of the signal, and the arriving wave angle of incidence, on the in the open air wire, and in the second wire, that is actually the ground, generates a current that travels on the direction of the arriving wave. The wave near the ground interacts with matter (ground) and it is reflected back, the vertical component has a positive phase and adds to the incident vertical component and generate the current that travel the transmission line (wire+ground). The Horizontal component has a negative phase and cancel the horizontal component and the result is no current is generated.
