Outcome of the VLA observations. Upper panels: images of 3C 328 at 1.5 GHz (left-hand panel) and at 5.5 GHz (right-hand panel). In both images, contours are at 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8, and 25.6 mJy beam⁻¹. Lower panels: slices across the lobes at 1.5 GHz (left-hand panel) and at 5.5 GHz (right-hand panel). North is on the left-hand side of each plot. The core has been bypassed by both slices.
