Hi James. Do you know if anyone (maybe you) makes
a compact FM antenna that does not require something
like headphone wires to act as the antenna? I know
obtainig a reasonable efficieny in a small form
factor at 88-108 MHz is tough (or impossible). Any
thoughts?

Hi Jess
About 20 years ago I bought from a mail
order catalogue a low profile compact receive antenna
that claimed to cover VHF FM and Band IV/V TV.
I will examine the case to see if there is a clue
to the manufacturer. I bought 4 at the time, and
I'm still using them as indoor antennas because
my apartment has no means of installing an outdoor
antenna for FM.
The size is about the same as
a pack of 20 ciggies (am I allowed to be non-PC
here?) or a lady's powder compact (ditto). It is
certainly effective, but to examine it by reverse
engineering, I would have to destroy it using a
hacksaw. I think it must use some kind of VHF/UHF
ferrite, with a coil would over it of a few turns.
