    The host appears to be SDSS J122118.88+362546.7, a faint galaxy with a z_ph=0.393 ± 0.0281. As per the classification comments left, the separation distance of the lobes appears to be ~ 1.24 Mpc, making this a #giant candidate. While there are no apparent First or NVSS references for this galaxy, there is an ALLWISE reference, ALLWISE J122118.92+362546.8.

    As to whether SDSS J122118.88+362546.7 is an #SDRAGN candidate, it has a fracDev_g, _r, of 1, and 0.771; and an expAB_g of 0.276 and expAB_r of 0.431 respectively. For c, the inverse concentration index, it has a figure of 0.319 for the g band and 0.325 for the r band.

    Seems to be maybe more elliptical than disk like, and faint. But open to any further suggestions or comments as to whether this could be an #SDRAGN candidate, in particular, with reference to the last ARG classification comment left.

    Here's a zoomed in image of SDSS J122118.88+362546.7 without the grid lines.
