Full Title

Full titles differ between systems:

IPC:

Electrically-short antennas having dimensions not more than twice the operating wavelength and consisting of conductive active radiating elements > Resonant antennas > with feed to end of elongated active element, e.g. unipole > Vertical arrangement of element > with top loading

CPC:

Electrically-short antennas having dimensions not more than twice the operating wavelength and consisting of conductive active radiating elements > Resonant antennas > with feed to end of elongated active element, e.g. unipole (H01Q9/44 takes precedence) > Vertical arrangement of element (H01Q9/40 takes precedence) > with top loading

No child classifications to compare. This is a leaf node in both IPC and CPC.
