Cutting the cable, lets talk options and media setups

I've been a cord cutter for years now, although that has partly been driven by living overseas for the last four years. Anyways, now that I'm back stateside I recently bought a leaf indoor antenna for local digital TV. I tried putting it in the attic but the reception is still pretty awful. Any recommendations? I only end up getting a few channels that even come in halfway decent and they come in and out.
