The radio sources 3C 345, 3C 418, and 3C 371 have been found to have secondary components located 2-3 arcsec away from the compact core. These secondary components emit about 10% of the total 20-cm flux, and have spectral indices steeper than 1.0. The radio source DA 267 shows no structure at 5 GHz, but is well resolved at 20 cm into a halo or asymmetric double of a few arcseconds scale size.
