Hello Roger, Dreamers, if we define near field as < 2 lambda we are talking about everything below 60 km.With this distance I woul be extremely lucky. I also do "walkaround tests" near my garden. But

Hi roger why dont you get him digging? :-) Yes, the loop will null the signal when turned 90 degrees but the signal was strong enough yesterday to be copied, just, when the loop was in its worst orie

Hi Rik, I think you'll find it's the H field that goes as the inverse 3rd power. The voltage in the Rx ant is proportional to this, and the power is proportional to the square of that. Thus the power

But if you want to reach more distance with an antenna of the same size (e.g. of your garden)and the same power, you could try such a TV transformer. Take a wire, as long as possible and as high as
