472kHz WSPR - more on the earth-electrode antenna

Overnight I continued using the earth-electrode antenna on 472kHz. I don't think it is any better than the short Marconi, but it certainly works pretty well, even with a short baseline of less than 15m.

The number of unique spots of my 472kHz WSPR signal has now reached 15 and I have spotted 19 unique stations with my best DX being DH5RAE (995km) using the earth-electrode antenna last night.

The earth-electrode antenna seems far more directional. Several stations orthogonal to the system did NOT copy me (or me them) overnight.
