We selected extragalactic sources with inverted spectra at 1.4 to 5 GHz, and observed ∼250 of them at the VLA at frequencies from 1.4 to 22 GHz and in some cases 43 GHz. Here we summarize the spectral index distributions, and report on polarization measurements and/or upper limits for a subsample of ∼35 sources (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
