Impossible!
That dish antenna is designed to work in Ku band (about 12GHz) and pointing to the sky. For FM, go to an old-fashioned electrical shop and ask for TV antenna which is formally known as Yagi-Uda antenna, which is used for receiving Doordarshan terrestrial transmissions. Mount in on your roof or the highest available point (higher is better), point it to the direction of FM transmission tower (fine tune direction later after connecting your radio), connect the usual flat TV antenna cable, run cable to your room, connect to FM receiver using the RF connector (same type of connector used in TV antenna input point). Then you're in business.
