Electrically isolated end-fed vs. center-fed dipole radiation
Testing confirms an end-fed dipole can energize the radiator nearly as well as a center-fed without need of additional counterpoise or other extraneous conductors.

The dipole antenna, how industry defines it
Is a dipole antenna defined by its behavior alone or also how one energizes it? The answer exists in IEEE and historical literature.
2 Meter, 5/4 Wave Antenna Revealed
We remove the mystique surrounding the 5/4 wave antenna comparing center and end fed approaches. One conclusion is the end fed 5/4 wave antenna shows little promise as a vertical antenna for terrestrial use.
