Abstract: Konusni antenski dipol je v območju napetostnih
vozlov znatno tanjši, kot v območju tokovnega vozla.
Obseg električnega vodnika je na koncih manjši od
štirih tisočink valovne dolžine, na sredini pa najmanj
desetkrat večji. Velike razlike v obsegih sredine
oziroma koncev dipola povzročajo med drugim znatno
povečanje resonančne dolžine konusnega dipola v
odnosu na linearni (cilindrični) dipol, celo za več kot
20%. Povečanje resonančne dolžine, racionalnejša
razporeditev vodljivega materiala glede na razporeditev
energije vzdolž dipola, boljša prilagoditev konusnega
dipola na impedanco prostora in znatno izboljšanje
stabilnosti električnih lastnosti (resonanca, Q) v
mokrem vremenu, zaledenitvi in drugih vplivih okolja,
povečujejo njegovo učinkovitost v primerjavi z linearnim
dipolom. Zamenjava linearnih dipolov v antenskih
sistemih s konusnimi (na primer pri Yagi-Uda antenah)
izdatno prispeva ojačenju oz. usmerjenosti.
