472kHz antennas

One of the last things I managed before being taken ill with my stomach bug was to use my end-fed Par long-wire HF antenna, suitably matched, via the preamp on 472kHz RX.  My very unscientific test conclusions are that none of these compromise antennas are much different. All copied about the same number of different WSPR stations at much the same strengths. As the tests were done on different nights conditions may have been different. The earth-electrode "antenna" in the ground is the easiest, so, for now, I shall continue using this on MF.

Maybe I should go back to bed as I still feel unwell.
