Radio Antenna Replacement.

My radio antenna is broken at least the long protruding element is. If i replace it with a bee sting style antenna or shark fin type out will it work? The original micra style one is too liable to breakage i feel and doesnt look that nice.

I also do not use the radio that much the current unit has only fm radio and cd player whicj is broken. Thus i will have to change that or get rid of it in the future. As i said i dont listen to much while driving.

Thus can the antenna be replaced with any other gadget than a radio antenna that might be more useful?
