As Alienhead says..
I think a simple antenna would be use null headphone jack from Radio shack, with pieces of wires soldered to Left and Right pinouts. or use some old headphone cable and let a few cms of wire stick out.
On the RX-51 Full schematics, page 8 ..
the FM antenna sources signal from the L and R pins of the headphone connector and sends to BTFM Module.

Why go to those lengths?
Just get a cheap pair of ten-a-penny headphones and cut the ear buds off.
Eureka!!!! You now have a purpose built 'T' antenna, just like the one that goes into the back of your Hi-Fi.

Ha ha.. I was imagining a slightly more subtle hack, opening the rear cover and solder two antenna segments to 'L' and 'R' connectors on the headphone jack.
I find the volume is really low - if you don't have the phone up close, even at full volume, you can hardly hear it...
Of course you have to turn it up. The same volume for tiny speakers milimeters away from your ears, vs larger speakers sitting on a desk or in your hands...of course you would need to turn it up. I think your expectations are a little much.
can any1 tell me, that y does the fm radio app needs the bluetooth to be switched on if it uses the headphones as an antenna...
The headphones are the antenna--that is all. The actual FM radio chip is the same chip used for bluetooth. They are combined. So it has to be 'turned on' for either to work.
