You can run speaker wire from your fm spring clips to any type of mast antenna. Just splice the speaker wire and touch it to whatever type of tv antenna you have. If it works, use electrical tape, or splice it if you know how.
If you have cable tv, you can also pick up fm stations just by touching this "speaker/antenna wire" to the cable itself.
MacmanNM is right, though. Any wire split and spread out behind your wall will work fine if the other options are too time consuming.
