It does NOT require a ground to be functioning, assuming the energy is
coupled into the radiator using some other way than an end-feed.
Of course it would be stupid to erect an over 600m high mast and not
connect it to ground, but that is for reasons entirely unrelated to
its use as a transmitter antenna.
So Marconi was not stupid.
