/ Abstract
Abstract The structure of the radio source RC B1146+052 of the ‘Cold’ catalogue is investigated by data of the MIT-GB-VLA survey at 4850 MHz. This source belongs to the steep spectrum radio sources subsample of the RC catalogue. Its spectral index is α = -1.04. The optical image of this source obtained with the 6 m telescope is analysed. The possible explanations of the complex structure of the radio components are considered.
