Low, horizontally polarized antennas are usually good for distances within a few hundred miles. However, 160 needs vertical polarization for consistent long DX.
The common myth that a dipole should be low for short distance work is simply not true. Indeed, the optimum height for high angle radiation (NVIS) is a quarter wave (120 ft on 160M) and only 2 dB down from that at 3/8 wave (180 ft on 160M). More important, raising a horizontal dipole or Yagi from a quarter-wave high to a half-wave high is good for almost 6 dB for vertical angles below 40 degrees!
