Default Transforner Theory

Hi All,

Info below from the following site----
http://www.ee.surrey.ac.uk/Workshop/...x.html#bhcurve

Unlike electrical conductivity, permeability is often a highly non-linear
quantity. Most coil design formulæ, however, pretend that it is a linear
quantity.

================================================== =======

My question is-

If I wind a transformer using the specified A sub L and then use that
transformer in a receive antenna where the voltages are very small, wouldn't
I be low on the curve and cause the transformer to function poorly
especially at the lowest frequency of the design?

Mike

PS Thinking about a Flag antenna, which has a small output signal.
