I think by "coax" he means RF modulation to channel 3/4 (or whatever
they use there), which indeed would look a lot worse than
composite/S-video.

FWIW, composite and S-video are almost identical in quality: the real
step-up is to component video, which can output progressive scan,
giving you 480 viewable scan lines in NTSC at one field per frame
(non-interlaced) instead of 240 per field at two per frame
(interlaced).  Unfortunately, this is pointless for analog TV since it
is broadcast at 480i, which is why I suspect TV capture cards don't
bother with it.  It makes a *huge* difference for DVD's, though.
