I was just wondering if there was ANY way to create (OR BUY) a telescopic FM antenna (OLD SCHOOL WALKMAN STYLE) that could be plugged in to the 3.5mm jack instead of headphones. The reason I am asking is because I think it would be more visually appealing for those warm summer Saturday nights on the patio and less of a chance for someone to say, "oh, what do these headphones go to?" and grab them and BOOM! the concrete has won the fight. I am also wondering if such a telescoping antenna would harbor better reception.

I have tried to make one myself using a gold plated 3.5mm to Coaxial adapter, a 30" telescoping antenna from radio shack and a push pin and it does work (I have to hold it together with my fingers)

Any Ideas
