Low-noise vertical mw bcb dx'ing antennas

WebA low dipole actually responds to ground-wave fields best off its ends! Here's an explanation for this peculiar behavior: The dipole has no response to the vertical component of a broadside ground wave because the electric field is perpendicular to the wire. The antenna responds only to the weak horizontal component. WebVertical-Dipoles. are (best case) 1/2 wavelong, and fed in the middle with 50 to 70 Ohm coax.
