Marconi was wrong about antennas having to be grounded to work.
I think that's a good thing. We wouldn't get signals from satellites
otherwise.
Actually, that begs the question "which planet is the real ground"?

Reckon we could hang a dipole all the way from the earth to the moon?
No.
What gain would it have and what frequency would it resonate on, I wonder.
Well, lessee... gain would be the same as any dipole, i.e. about 1.76dBi
not considering resistive losses because you did not specify a conductor
size. Resonant frequency would be ~.372 Hz. This does not include the
"capacitive hats" of the earth and moon.
73, Ian.
Where would "ground" be?
