On the other hand, if the load is not matched to the transmission line,
which happens in the real world a lot, a transmission line that is a
multiple of 1/2 wavelength will at least make sure that the antenna's
feedpoint impedance is not transformed by the transmission line, and that
the apparent resonance does not change. This may make no difference (it
doesn't here) but may help to explain the idea of the "sweet spot."|

A large change in transmission line loss can also cause SWR to be gradually changed along the line, but it is a smooth slope and does not have peaks and valleys every 1/4 wl.
