Multifrequency radio observations of two large radio galaxies with large north-south angular extensions were mapped from 1.4-10.6 GHz for total radio power and linear polarization. The data on 0634 - 20 led to calculation of a galactic Faraday rotation measure of under 4 percent over 7 arcmin, and no more than 25 percent over the entire 15 arcmin length of 0634 - 20. For 3C 445, a steepening spectral index was found transverse, but not along, the long axis. A k-factor value of 5-20 at a temperature of 100 million K was projected for the relativistic particle populations.
