Abstract

The giant radio galaxies NGC 315, DA 240, 3C 236, 3C 326, and NGC 6251 have been observed at 92 cm and 49 cm wavelengths with the Westerbork Synthesis Radio Telescope (WSRT) and at , 6.3 cm, and 2.8 cm using the Effelsberg 100-m telescope. These objects all exhibit strong polarized radio emission across the entire radio frequency domain. Their spectral index distributions are very complex, with significant variations across individual objects.
