Abstract: We have mapped the head-tail radio galaxy, 3C 129 at 240 and 610 MHz using the GMRT and studied the detailed morphology and spectral index variations in this object. This is the first attempt to observe a sample of head-tail sources at low frequencies. We find weak spectral steepening as we go away from the head along the jet. The Crosspiece has a spectral index of 0.7 (Sv v-) and is flatter than the spectral index estimated by Lane et al. (2002). We also see a low surface brightness, diffuse feature at 240 MHz and could be a possible radio relic candidate (see Figure).
