We just have rabbit ears, too. What I've found is that by fiddling (moving to different spots, etc), you can usually get one or two channels to come in decently, but they won't all come in that well. On our tv we just fiddle with them whenever we want to watch a program on a specific channel.

I don't watch much tv either, so paying for cable seems like a waste! Plus, I don't need another sedentary distraction, I've got enough already!
