I got an amplified, directional antenna that I put by a dormer window in my attic.
Then I aimed it according to the results of this website:

I get 40 or so channels (I don't watch all of them because so many are "junk" or spanish language channels). However, they ALL come in crystal clear.
I used an amplified spliter to run the coax from the cable to 6 rooms in my house.
