Thinking about WH2XIL’s ground-based dipole for 188.2 kHz, I read with interest John Davis’ column On the Air in the latest issue of Lowdown, just received (via email) in the last day or so. In it, John states, regarding WH2XIL’s ground-based dipole: “because its antenna is a ground-based dipole, which at LF forms the equivalent of a loop antenna in the Earth itself, complete with high angle radiation comparable to an elevated physical loop.” I am (very slowly!) working on a beacon for 178 kHz and intend to use a 50’ loop (- short length of feedline) which I had planned for a horizontal orientation well above ground. But now considering John’s comment, I’m wondering if the same loop laid on the ground itself might work? Or would ground mounting only work with a dipole where the 2 “halves” were separated thus forcing the ground to become part of the loop circuit? Would appreciate any thoughts.
