Mal I worked WD2XSH/35 in South Dakota a couple weekends ago and heard him a couple times since. Here's his e mail to me on his setup. Think it should read one leg N/S and the other is E/W. Note that
That's how submarine communications antennas work on ELF (81Hz or whatever). A very long wire is grounded at the far end. the skin depth of poor conductivity ground results in a loop antenna with t

Ref ur calculations Rik with my inv L I am running only 0.565 w erp. Have u got ur wires crossed. How do u get ur figures for a dipole at 100 ft high on 500. as 0.25 ohm Rr I am not looking for a QRO
Dear Mal, LF Group, Interestingly, if you do an EZNEC simulation of this antenna, it produces an upwards-directed, horizontally polarised lobe as you would expect. But it also produces vertically pol
Jay, Mal, I think that a "low" dipole is only meaningfull above poor soil. At 20 ft (6m) above a perfect ground the radiation resistance would be only 0.25 Ohm. But in contradiction to a short vertic
Rik, Jim & co Tnx ur observations. It seems there is not much advantage dipole v 1/4 wave inv L. My soil is good therefore the 1/4 wave is probably better plus the low angle and radiation resistance
