I took a look at the antenna you're describing...

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

My thought would be that, at MW frequencies, the 'wire' part of the antenna
is pretty much 'lumped' (no significant phase change along its length), so
you have a standard ferrite rod antenna that you're hooking up via a long
piece of hookup wire. That's a reasonable enough antenna.

As you approach HF, the 'wire' part of the antenna starts to become active
and the two signals combine.

Still, this is very much a 'hands waving' explanation; hopefully someone
else will have a more solid response.

* Does this Idea actually Work ?
* Or is this Idea just so much Antenna 'hype' and Sales Marketing

I imagine it works as well as either antenna alone (the ferrite rods or the
long wire) would, and the real question is... do the two together produce
any significant additional gain? I suspect not (much), but even if so,
sometimes a wideband standard gain antenna is more desirable than a higher
gain single bander.
