Kpc-scale triple active galactic nuclei (AGNs), potential precursors ofgravitationally-bound triple massive black holes (MBHs), are rarely seenobjects and believed to play an important role in the evolution of MBHs andtheir host galaxies. In this work we present a multi-band (3.0, 6.0 10.0, and15.0 GHz), high-resolution radio imaging of the triple AGN candidate, SDSSJ0849+1114, using the Very Large Array. Two of the three nuclei (A and C) aredetected at 3.0, 6.0, and 15 GHz for the first time, both exhibiting a steepspectrum over 3--15 GHz (with a spectral index $-0.90 \pm 0.05$ and $-1.03 \pm0.04$) consistent with a synchrotron origin. Nucleus A, the strongest nucleusamong the three, shows a double-sided jet, with the jet orientation changing by$\sim20^{\circ}$ between its inner 1" and the outer 5.5" (8.1 kpc) components,which may be explained as the MBH's angular momentum having been altered bymerger-enhanced accretion. Nucleus C also shows a two-sided jet, with thewestern jet inflating into a radio lobe with an extent of 1.5" (2.2 kpc). Theinternal energy of the radio lobe is estimated to be $\rm 5.0 \times 10^{55}$erg, for an equipartition magnetic field strength of $\rm \sim 160\ \mu G$. Nosignificant radio emission is detected at all four frequencies for nucleus B,yielding an upper limit of 15, 15, 15, and 18 $\rm \mu Jy\ beam^{-1}$ at 3.0,6.0, 10.0, and 15.0 GHz, based on which we constrain the star formation rate innucleus B to be $\lesssim 0.4~\rm M_{\odot}~yr^{-1}$.
