The DC case is fundamentally different because, as you say, there is no wave. The impedance of the "feedline" doesn't matter at all, either, ideally you'd have a 0ohm wire to take your DC power from source to load. And no antenna will radiate any power at DC, either. None of this is really relevant for a discussion about RF. Electrodynamics are very different from Electrostatics.
