You know, I've wondered about that, too. The closest to explaining
that I've conjured is that the electromagnetic field works up
there, but I can't imagine how the electrostatic field from the
transmitting antenna could work on a space antenna. But antenna
design has always been black magic to me.

Basic Nicola Tesla. Resonance. Has nothing to do with ground or
waves travelling through space. An antenna sets up a field by
resonating at the frequency of a connected generator. An antenna
samples energy from the field in a similar manner and this can be
detected.

But nonresonant antennas work quite well, probably even in space.
Resonant antennas work better, but your explanation doesn't account
for the long-wire antenna that works on 19M and 49M too.
It's in the field and absorbing energy. The lack of resonance
requires more amplification.
