FO&A,

Here is my Question: Is there any sense in putting a Ferrite Rod
at the Far-End of a Random Wire Antenna with the Wire from the
End of the Wire Antenna Element 'wrapped' around it in a
"Tuned Coil" to improve the AM/MW Band Reception ?

* Any 'theory' behind why this Idea might Work ?

* Does this Idea actually Work ?

* Or is this Idea just so much Antenna 'hype' and Sales Marketing

I'll pick door number 3, Monty.

If the far end of the antenna were grounded there might be some pickup
at the self resonant frequency of the ferrite coil, and it would be
a good DC ground at the far end that might reduce some noise.

If it's not grounded, it's just a convenient weight to toss it into
the trees, because there's no loop in the circuit for any current to be
coupled into, and a small isolated ferrite coil isn't going to produce
a voltage differential to ground that could couple through capacitance.
