Which antenna (over the air) I could use inside and get great signal?

I live in Costa Mesa, CA. Thinking about dumping dish and getting over the air antenna. I have HDTV TV and don't have much time to watch TV. Can't put antenna on a rooftop and my apartment balcony (2nd floor) is facing South and towers within 30 to 40 miles are North. I need suggestions and recommendations from you how to solve this issue. Thank you!
