Say, for purposes of illustration, that the near field ends at 1 wavelength.
At 2 MHz, that is very roughly 530 feet . At 14 MHz it is about 64 feet.
At 30 MHz, it has shrunk to ~32 feet.

But, that seems to only be effective up to 3 or 4 MHz, due to the
wavelength
factor, i. e. the near field shrinks as you go higher in frequency.

REALLY? How does it do that?
