That's one hell of an inefficient antenna. At a ~1MHz center frequency it's basically just a dummy load (resistor) that happens to radiate a little. 300 Watts

That's one hell of an inefficient antenna. At a ~1MHz center frequency it's basically just a dummy load (resistor) that happens to radiate a little. 300 Watts at those frequencies on a long run of speaker wire with a matching transformer/unun at one end could get you 100s of miles during the day and 1000s of miles at night.
