  We have identified a large (~200 kpc), powerful double radio source whose
host galaxy is clearly a disk and most likely a spiral. This FR I radio galaxy
is located very near the center of the RC 0 cluster Abell 428. The existence of
such an object violates a fundamental paradigm for radio loud AGN. In paper I,
we showed that this object was most likely a spiral host with optical line
ratios and colors consistent with an AGN. In this paper, we present new, higher
resolution radio imaging, a radio/mm continuum spectrum for the nucleus, a
detection of HI absorption against the bright radio core, an upper-limit to CO
and the gas mass, and 70 optical redshifts. We confirm the existence of a radio
jet at 20cm extending 42 kpc into the southern lobe. At 3.6cm, we also detect a
nuclear jet similar in length to that in M87 but 10 times weaker. We believe
that this is the first detection of a radio jet on these scales in a disk or
spiral host galaxy. The nuclear radio spectrum is similar to many blazar or QSO
like objects, suggesting that the galaxy harbors an imbedded and obscured AGN.
We model a turnover in the spectrum at low frequencies as Free-Free absorption.
We detect very strong and narrow HI absorption with nearly the entire 20 cm
core continuum absorbed, implying an unusually large optical depth (tau~1). We
suggest that the nucleus is seen through a disk-like distribution of ISM gas,
possibly through a spiral arm or a warp to account for the high column density.
  From the radial velocities, we find that A428 is in fact made up of at least
2 clumps of galaxies separated by 3300 km/s, which are imbedded in a nearly
continuous distribution of galaxies over 13000 km/s in velocity. Thus, the
environment resembles a poor group within a filament viewed end-on.
