. The lower the frequency, the more power is needed.

Transmitting aerials are less efficient when their length is only a
small fraction of the wavelength, hence the need for transmitters that
produce lots of VA (with all the losses that entails)..  Receiving
aerials are similarly affected, but nowadays, with cheaply-available
low-noise gain, the long-wave reception limit is usually set by the
noise floor of the location.
