The radiation was "35 db" compared to what reference value?
BTW, a single, linear radiator cannot generate a perfectly spherical
radiation pattern, no matter what your model tells you.
Even an "infinitesimally" short, center-fed linear dipole has a figure
8 radiation pattern with a directivity (gain) of 1.5 X, or 1.76 dBi
