I was following the whole discussion about the so called "earth-mode" and the used antennas with interest. Mal told us that he sees those antennas as "lossy dipoles" while others stated they are "true" earth-antennas. I don't have the theoretical background to tell you why but out of my feeling, all those antennas described remind me on the well-known Beverage-Antenna system. Two wires of any layout, diameter, height and length terminated by a "resistor"...the soil. Could that be a way we could look at this kind of antenna? And if so, what would it explain? 73 OE3GHB Gerhard
