Hi folks.
I'm looking for information about
very short FM radio antennas. My application is
a commercial product that is wearable by the user,
or that can maybe be embedded in a portable device
that will not require the wires from a plug-in headset
to act as the antenna. Any ideas? I've searched
through a lot of stuff on the web and can't find
anything useful.
Your thoughts would be appreciated.
Thanks - Maxwell

Hey Max, I don't think you're going to find anything
really useful. If you take a look at what has been
around for decades, the long wires work best. The
quality of the antenna seems to far outweight the
quality of the receiver for most case. I have a
car with a $350 FM tuner that can't pull in stations
my PoS Escort will with the factory radio. In fact,
my Escort can get both AM and FM stations that none
of my other cars or my home stereo can get (home
stereo only uses 300-ohm dipole). The headphone
wires that constitute the FM antenna for iPods,
Walkmans, etc., are really lousy, as anyone who
has tried to use one can tell you. Forget about
picking up a station in a metal/concrete building.
The little stubby whip antennas built into headset
with receiver built in are crappy too. Sorry
to be the bearer of bad news, but I don't think
you can get there from here.

Thanks Fred. That's pretty much what I thought,
but I know that somewhere I have read about people
doing research into very effective short antennas.
If anyone else knows of anything, please let
me know.
