| May 3, 2021 at 14:34 | comment | added | Phil Frost - W8II | I'd put it this way: a small dipole and a small loop have identical radiation patterns in free space (and thus, identical directivity), but complementary polarizations. Either can be omnidirectional or figure-8, depending on orientation. | |

Horizontal dipole above ground is mainly sensitive for skywave reflected signals; directivity is better for higher frequencies since the arriving angle (signal above the horizon) is lower. Loop antenna has "figure-8" directivity. mwcircle.org/mw_antenna.htm The combination of E and H field gives cardioid pattern. | |
