Hi Rick. 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.

This means that 90 degree each direction will get maximum gain. Try to make sure this phenomenon. 73 7L1RLL Rick, (but not Rik) |
