The main observational properties of AGNs at centimeter-decimeter wavelengths –- spectra, variability on various time scales, polarization and milli-arcsecond maps –- are in agreement with calculations in a jet model with a strong quasi radial magnetic field. Typical spectra and VLBI structures can be explained by a simple case of a straight line jet, unlike the degree of the linear polarization. Curved jets in the model allow decreasing the polarization to observational values as well.
