Maybe you've decided to stop subscribing to a digital satellite cable provider to save money, but still have one of those large pizza sized dishes sitting on top of your home/building doing diddly-squat. Combining it with a modestly priced $59 rooftop antenna, the satellite dish can see new life as a broadcast signal amplifier, helping bring in a selection of free local over-the-air HDTV shows...
Reddit reader Josh Zastrow purchased, installed, and secured a $59 RCA ANT751 Compact Outdoor Antenna in front of his old DirectTV satellite dish, effectively amplifying and strengthening the reception of all the free local over-the-air signals required made available by federal law, saving himself $82 in the process (and apparently bringing him a clear dose of Ellen each day).
Depending upon whether you've already got coax cable coming down from the rooftop, this hack might prove a very simple afternoon job (otherwise, I'd recommend hiring a handyman equipped and insured to work from the rooftop to drill through walls/ceilings to snake coax cable down to the living room).
