A reinvestigation is conducted of the reported tendency for the extended radio structures associated with bright elliptical galaxies to be oriented preferentially along the optical minor axes. It is found that such a tendency exists only for those galaxies in which the compact radio cores coincident with their nuclei are quite prominent. If the galaxies are divided into two groups according to whether their cores account for less than or greater than 10 percent of the total flux density at 2.7 GHz, the angle phi (between the radio axis and the optical minor axis) appears to be uniformly distributed between 0 deg and 90 deg for the former, but is nearly always less than 30 deg for the latter group. One possible explanation is that the radio emission from compact cores suffers thermal absorption by ionized gas that is distributed differently in the two groups.
