Re: Ferrite antenna design in older portable radios


A lot of European radios from my collection have unusual windings, and excellent performance, including radios with coils at both ends of the ferrite.
Some time ago I looked for internal  Online photos of PL-600 and PL-450 radios which are sharply directional. I could not see anything special about the windings on the ferrite.
