Any change in impedance at the end of a wire, different from the rest of a transmission-line-like wire, will reflect some current.

An impedance matched resistor at the ends of a dipole won't reflect a current wave, but will be highly lossy, which for an dipole antenna, is usually considered not working well. One usually wants EM radiation, not thermal radiation.
