Living on a hill can be tricky as TV signals (especially on UHF bands) do work on "line-of-sight" concept. Get antenna as high as you can to ensure best reception, and play around with its direction.

It depend how far away you are living from TV stations. The further you are, you will need bigger antenna that have higher gain. Radioshack have few choices in that regard, and here is one that is good general reception antenna for VHF and UHF bands:
