Set up a room aerial inside your attic, if you can. It sounds like you don't want the hassle of mounting it to your roof (or maybe you can't if this is a condo, or you're renting the house). But the attic is close in performance to the roof, and no indoor aerial in our listening room is probably going to touch a attic or roof mounted aerial. Radio Shack used to have a FM aerial for $20 that you could use. On the upside, there will be no ugly aerial visible from your room or from the outside.
happy hunting!
