The asymmetric depolarization seen in powerful extragalactic double sources with one sided jets may be explained in terms of differential Faraday effects in a halo of gas surrounding the source, provided the halo has a core-radius ~30–100 kpc, and contains a magnetic field of order >1 μGauss tangled on a scale <5 kpc.
