Where to get FM/AM antenna?

Please help me to find the little antenna that usually comes with the receiver. I recently bought an s/h receiver with no antenna included. I've been looking for it everywhere but no luck. I don't want to big one, I just want the wired one, that comes with the receiver, if you know what I am talking about.
Folded dipole antennas should still be available at Rat Shack
What you want is a dipole antenna - Try any Radio Shack

FM and AM antenna are different. The receiver may have a built-in AM antenna.
