Birdcage antennas often get mistaken for the fan dipole variety, these use thinner cables of slightly different lengths to broaden the resonance.

As fascinating as "skin effect" is to whatever Yagi / Moxon / Spider / Delta / Quad etc array we discuss then I still believe the Cable thickness is inversely proportional to the posters IQ... :p
