Can anyone recall this equation, I know it was mentioned on this reflector before...
 
What is the output voltage for an untuned small loop into an arbitrarily high impedance?  It is proportional to H, and presumably F^2, and I seem to recall it is an absolute value, virtually un-influenced by losses, conductor diameter etc.  Therefore can be used for accurate H field (and hence far field radiation) signal strength measurements.
