That makes sense, Ray. What made me think of the probe pair was a reminder of playing with very short dipoles when I was testing home-made baluns, Just for fun, I put a couple of feet of wire on each end of the primary winding of the balun, with coax feeding a receiver connected to the other. This was indoors, testing at HF (Probably WWV on 10 MHz). Changes in the noise with orientation suggested directionality, just as one would expect. This would be very very inefficient at LF, but if the two elements were coupled actively. I know I had seen something like this before and this article for VLF reception www.vlf.it/cr/differential_ant.htm, but the mode of use is slightly different in the way noise rejection is intended.
