dc.description.abstract	Analysis of Giant Metrewave Radio Telescope low frequency data for an X-shaped source, 3C 223.1 has revealed an unusual result as discussed earlier by Lal & Rao (2004). The radio morphologies of it at 240 and 610 MHz show a well-denfied X-shaped structure with a pair of active jets along the north-south axis and a pair of wings along the east-west axis, that pass symmetrically through the undetected radio core. The wings (or low surface brightness jet) seem to have flatter spectral index with respect to the high surface brightness jet. This clearly shows the value of mapping the sample of X-shaped sources at low frequencies. Here we present our preliminary results for two more such sources	en
