outdoor antenna setup?

so here's the deal.... i'm a cable tv child.... never had the "leave it to beaver" antenna on my home. however, we are canceling the cable today and i want to put up an antenna this summer.... question is, what all do i need? do i put up the antenna and just tie it back in to the existing cable lines? is there something else i will need at the end of the cables in the house (box, convertor?)? i do know i will need the new convertor box for one of my tv's the other i believe has a built in tuner.... so i should be ok.... is there anything else i need to know? i couldn't find a site that went through the entire set up process.
