<DIV>Hello group,<BR><BR>It is an "idée fixe" that a horizontal wire must
radiate a horizontal polarized EM-wave.<BR>A nice example of a mechanical
horizontal construction that radiates a vertical polarized signal is the DDRR
antenna.<BR>So a large horizontal topload close to ground will in most cases
improve the antenna efficiency (reduce the loss resistance ... footprint
theory) but the radiated signal will be nevertheless mainly vertical
polarized.<BR><BR>73, Rik ON7YD<BR><BR>At 17:47 5/01/2004 +0100, you

<DIV><FONT face=Arial size=2>I agree with your observations. Some are being
misled by computer modelling and antenna theory not applicable to the type of
small LF antennas used by radio amateurs. </FONT></DIV>
