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!
