Extragalactic radio sources associated with elliptical galaxies and quasars exhibit a rich variety of structures on scales ranging from < few parsecs to over a Mpc. The sources with extended (> tens of kpc) structure are often classified into the low–luminosity FRI sources which usually have diffuse outer lobes, and the high luminosity FRII sources which tend to have bright hotspots at the outer edges. (Miley 1980; Bridle & Perley 1984). The FRI and II types differ in a number of other aspects as well such as the structure and magnetic field orientation in the radio jets, morphology of the parent optical galaxies and their environments (Bridle & Perley 1984; Lilly & Prestage 1987; Owen and Laing 1989). It therefore seems unlikely that the two FR classes either represent different phases in an evolutionary sequence or are caused by differences in orientation or the supply of energy to the outer lobes.
