Abstract
We present new radio images obtained with the Australia Telescope Compact A rray (ATCA) and the Very Large Array (VLA) for a group of 14 galaxies belon ging to the 2-Jy sample of radio sources. The new images improve the data a lready available on these objects and, in general, the database that we are building up on the sample. They will also be used for follow-up work where radio-optical comparison will be done. We briefly discuss the core dominance parameter (R) for the objects for whi ch the new data have gis en new information and, in particular, for broad l ine radio galaxies (BLRG). One of the BLRG does not show a core, even at 3 cm. and this is at variance with the general tendency of BLRG to have relat ively strong cores. The depolarization is also discussed for a group of sma ll double-lobed radio galaxies.
