There are several reasons why maximum field strength and minimum SWR don't
occur at the same points, necessarily. The field strength can be
considered
part of the "efficiency" of the overall system. SWR just relates to the
match
between the feedline and the coax. Think of the dummy load example; it
might
exhibit close to a 1:1 SWR but radiates little power.

A dummy load is also physical proof of the existence of an isotropic
radiator (albeit a rather poor radiator g).
