The FM radio band is right smack in the middle of the VHF TV band, so basically any VHF TV antenna will work decently for FM radio (unless there's a notch filter to cut it out, which seems rather pointless to my limited understanding but could be done). Likewise, most simple antenna amplifiers for TV use would also work well with FM radio.
There may be a little bit of fiddling needed to adapt and impedance match the feedlines to the radio, but even that should be pretty simple. I think most FM receivers these days expect a 75 ohm antenna impedance, and I believe that's also standard for TV coaxial inputs.
