Abstract Radio flux-density measurements for a large sample of millisecond pulsars at a low frequency of 102 MHz are presented. Using higher frequency measurements, we construct their spectra in the frequency range from 102 MHz to 4.8 GHz, the widest one studied to date. The spectra of millisecond and normal pulsars have been found to differ. The spectra of millisecond pulsars have no low-frequency turnover typical of normal pulsars. The absence of a low-frequency turnover in the spectrum suggests that the emitting regions of millisecond and normal pulsars differ in geometry, which we interpret by deviation of the magnetic field from a dipole one or by compactness of the emitting region.
