In examples and comparisons we would feed the same power, at the base of the 
quarter wave antenna, loaded or otherwise we will get the same current. What 
happens to it along its "travels" along the radiator, that's what defines 
efficiency. The longer portion of the radiator radiating maximum possible current, 
the better efficiency, more signal out.
ON4UN explains that nicely using cosine formula.
