The first few contributing eigenvalues for any angular sector having a wide range of included angle are presented in easy to use graphical form. It is shown that it is only these first few eigenvalues that contribute to the current in a region very close to the tip itself. Beyond this region the GTD may be used to obtain the current thereby overcoming the need to use large numbers of eigenvalues and eigenfunctions. The combined eigenfunction-GTD technique is then applied to find the currents and resulting radiation fields.
