Abstract
Observations have been made of the radio galaxy 3C 166 at 1.4 and 4.9 GHz using the 'A' and 'B' configurations of the Very Large Array to provide an angular resolution of 1.6 sec at both frequencies. The source has a basically double structure with strikingly dissimilar lobes. The south lobe is brightened along its outer edge, with a prominent hot spot, whereas the north lobe is relaxed in appearance with more feeble interior brightness maxima. The south lobe is strongly Faraday depolarized at 1.4 and possibly also at 4.9 GHz, but there is no measurable Faraday depth in the north lobe. The results are used to estimate magnetic field strengths and thermal particle densities in the lobes.
