Hello,

I have a portable music player (MP3, etc) with a built-in FM
transmitter. The original transmission antenna is a thin foil thing
shaped like a very elongated letter 'E'. It has terrible range;
aftermarket transmitters will nearly always do better.

Could somebody point me in the right direction for making a suitable
replacement that will still fit inside the very tight (2"x3"x almost
nothing) available space? Is it possible, for example, to make a
simple (1/48th wave?) dipole antenna of some sort that will be an
effective transmitter?

Many thanks for your help to one entirely ignorant in this field.
