"Cecil Moore" wrote Since the forward current and reflected current are equal in magnitude and opposite in phase at the ends, they act like transmission line currents and the magnetic fields cancel at the ends. They are in phase at the feedpoint - hence the maximum radiation at that point. See what Richard Harrison wrote: "At the open circuited ends of a resonant antenna there is almost double the forward voltage but zero total current due to cancellation of the forward and reflected currents at the open circuit. At the open circuit in the wire, all the energy in the wave is transferred to the electric field." What I wrote agrees with what Richard H. wrote and vice versa. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |
