The spectral-index distributions of 3C 28, 76.1, 186, and 319 and the polarization properties of 3C 76.1 are investigated using multifrequency observations of each source made with the One-Mile and 5-km telescopes. Results show that 3C 28 has the structure of a Fanaroff-Riley class I source, but it is 10 times more luminous than expected for this class. 3C 76.1 is also found to be a Fanaroff-Riley class I source, although it contains a feature which has the properties of a hotspot. The spectral-index distribution in 3C 76.1 is complex with the magnetic field perpendicular to the axes of the jets while the polarization properties are consistent with a tangle-field model. 3C 319 is found to be a double source with only one hotspot rather than being a tail source. It is proposed that the different properties of 3C 28 and 76.1 are due to their different environments. This explanation is shown to be consistent with a general scheme which can account for all the observed dependences of source properties on cluster membership.
