We report on new full-synthesis imaging of intensity and linear polarization structure of the radio emission from 3C 58, one of the most beautiful and interesting pulsar wind nebula known to date. The observations, acquired with the Karl G. Jansky Very Large Array in the 2-8 GHz wide range of frequencies, cover a much wider spectral bandwidth than any other used in previous studies of this iconic object. We used the new data to revisit the distribution of the magnetic field and investigate the spectral transition in the individual pulsar wind nebula features.
