We present sensitive images of the microquasar GRS 1758-258 at two different radio wavelengths. The positions, flux densities and spectral indices of the central source and the extended radio lobes are reported. Our results confirm the synchrotron nature of the radio lobes. We also present a very deep radio image of the jet flow at arcminute scales. The source VLA-C, previously proposed as the exciting source of the system, is found to coincide with the Chandra position.
