For the temp do the good ole trick. Try sticking a wire in the fm slot and extend it. You should get reception. There are radio kings here who will advice better than me !
Are you looking for something indoor or outdoor? Indoor antennas are not that effective. You can just use a wire to DIY to buy something readily available. If you are close to radio stations, simple wire works fine too. Get a wire of about 3mtr and plug it in. If the wire can be placed vertically near the window or outside the window, it is better.
