Yes I think I can confirm that. I connected my signal generator to the earth antenna (300mV p-p at 150 KHz) and walked about with my long wave transistor radio and found maximum signal when the ferrite rod antenna was 90 degrees to the wire, which confused me. I also connected it to the inverted L and got very little signal from it at all, even when standing underneath it. I'm busy tomorrow, but I will do a lot more tests this weekend and I will lay out another (slightly shorter) earth antenna 90 degrees to the first one. 73, Tony, EI8JK.
