I don`t have time to verify the answer but will respond from memory. The
far fields decline linearly in direct proportion to the distance from
the noise source while the near fields decline in proportion to the
square of the distance from the source. So an ability to discriminate
against local electric near field noise is a destinct advantage separate
and apart from any directivity of a loop.

Terman always says what he means and means what he says. He was a
sucinct and excellent writer who mastered his topic.

Unable, at least at the moment, to test/verify that, I am inclined to
believe what you present. It sounds logical anyway. I will keep my
eyes open for data on the subject. :-)

Warm regards,
