45mm Long ferrite Rod 4mm Diameter

This is one item
of mini ferrite rod antenna intended for use in a small AM radio.  The length is 45mm and the diameter is 4mm.  You can click on the pictures for bigger images, the wire isn't included:

4mm Diameter
Ferrite Rod End60 Turn Test Winding on 4mm Ferrite Rod

With the coil winding of 60 turns of multi-stranded copper wire as shown in the picture in parallel with a 1000pF capacitor, this resonated at 497 kHz with -3db points either side at approximately 496 and 499 kHz, to the best measurement that I could make.  That at least shows that it is genuinely high Q material intended for LW and MW tuning inductor use, and the Q of that coil would be 165.  I used 100 turns on a paper former to tune most of the MW band with a standard 200pF capacitor attached to a Useful Components transistor radio kit as shown in the pictures below.  This needed a bit more gain than the much larger rod, but the radio still tuned sharply.  If you're trying to make a matchbox radio design with a TA7642 or ZN414, this could be ideal.

With a much bigger coil winding, this could be used to pick up audio frequency signals from an induction loop system or telephone receiver if connected into a typical microphone input.
