How to replace your cable bill by a house cleaner?

Since a couple of years, I want to get ride of the cable because the cost doesn't justify its usage but my wife still want to listen sometimes to traditional TV. I made a deal with her. I have exchanged the cable bills to a maid and air HDTV. I have invested CAN$163 to buy the material required to set-up a digital antenna and 4 hours to install it. It will take me only 4 months to recover my investment and then my saving will paid 50% of my maid bill per months. What do you need to buy to do the same? (special thanks the Steph)
