The plots of the Poynting vector might serve to show which part of the wire is mainly responsible for creating the radiated field. The movie of the modulus, |S|, does not give a clear answer, since at close distances the pointing vector reaches high values along the entire wire. The fact that |S| is high along the entire line just means that energy is shifted between the endpoints and the middle region (electric and magnetic field respectively).
