The only antenna that meets that requirement is a vertical dipole which is usually a short range antenna. Unfortunately for that idea, US TV broadcasting broadcasting uses horizontal polarization as its default so a vertical whip doesn't receive very much.
I've tested a number of antennas that claim to be "omni-directional" but they just aren't. One in particular, an RCA flat panel for indoor use, exhibited peaks and nulls separated by as much as 15-20 dB when rotated which is a long, long way from being "omni" or "all" directional.
