Several posts on the TopBand email reflector recently have mentioned station 1BCG in Greenwich, CT, the first radio station to transmit a message across the Atlantic on short waves i.e. on frequencies with a wavelength less than 200 meters.
QST magazine 1922 has articles about the first trans-Atlantic QSOs made by hams in 1921 and the antenna they used was essentially identical to the antenna being built at TF4M, except that rather than using two elevated radials at the bottom, they used a fan of around 30 elevated radials.
