Long ago when Radio Shack sold TV antennas I bought a medium priced one just for FM. FM exists, IIRC, between channel 6 and 7. That is the old analog ones not the digital ones.
If you can find a used TV antenna someone doesn't need any more they are good. Just call it a ceiling decoration. Hey, Elvis had a parachute covering the ceiling of the pool table room at Graceland. You will just be a bit more Avant Garde than he was.
