The size and power of the Michigan array (which is buried by the way), is a
reflection of the fact that losses in the "antenna" dominate, and to
actually radiate (that is, start propagating) roughly a watt of RF takes
several Megawatts of input power to the radiator. Building a suitably high
Q (i.e. low loss) electrical resonator at 15 Hz is no easy matter.
(mechanically, it's easy to get high Q at low frequency, consider a
pendulumn operating in a vacuum).
