1. Topband: Twin Lead Marconi Antenna (score: 1): Author: Garry <g.drummond@verizon.net>; Date: Sat, 13 Jun 2009 14:10:37 -0400; Years ago, Bill Orr wrote a book titled Wire Antennas. On page 104 in this book, he described an inverted-L type of antenna called a Twin Lead Marconi built using TV win lead in the L section with a; /archives//html/Topband/2009-06/msg00047.html (6,578 bytes)

4. Re: Topband: Twin Lead Marconi Antenna (score: 1): Author: "Jim Brown" <jim@audiosystemsgroup.com>; Date: Mon, 15 Jun 2009 09:42:39 -0700; I disagree. Radiation is the result of CURRENT. Your analysis assumes that current is evenly distributed along the wire. It is not! The high current parts of the antenna are still vertical.

5. Re: Topband: Twin Lead Marconi Antenna (score: 1): Author: Ross Primrose <aj4ll@aiko.com>; Date: Mon, 15 Jun 2009 14:54:23 -0400; Citation? That's still the working theory in Low Band DXing. Ground RESISTANCE is a factor of the radial system. Ground LOSSES are related to the ratio of ground resistance to radiation resistance. R; /archives//html/Topband/2009-06/msg00052.html (8,659 bytes)

Try: http://www.w8ji.com/radiation_resistance.htm Tom quite clearly shows that the 4:1 step up in the feedpoint impedance does not change the current flowing in the ground.
