This is an interesting experiment and my first thought would be that it is behaving like a Beverage antenna. At 23.4kHz a 25m long wire less than 0.2% of the wavelength. It would be the same as claim

Hello Mal, I am not a great technician but even to me it seems clear, that it's an obsolete discussion. I do not think that on this low frequencies (vlf) it makes a remarcable difference if the wire

Hi Mal & LF Your comments prompted me to carry out some simple tests today. I layed out a 25m length of Thompson RG 214/U double screened coax on the lawn and connected the centre conductor at the fa

Gerhard Yes the antennas described by Stefan and Roger and others are of the LOSSY variety and similar to Beverages. I have made this observation before. I cannot see how these elevated antennas can

Hi Mal. It is most definitely directional or at least my permanent earth dipoles are. I have two at 90 degrees laid out as a cross with the radio shack at the centre. Both have wires 80m long laid on
