Over the years, a few products have been marketed that attempted to use the power line as an antenna. Off the top of my head, I'm not aware of any currently on the market.
A fundamental problem with the concept is that no electrician is going to attempt to arrange the wires in the wall so that they would form an efficient, functional antenna. Then, the motors and electronic devises connected to the power line are generators of interference to varying degrees. Finally, if there is a failure of an insulating component in the 'antenna/power-line coupler, you could have 120 VAC connected to the TV antenna input. That seems like something I would not want to happen. Bottom line, the products came and went the way of other 'gimmick' products that may have worked for a few, but were marketed as 'miracles'.
With no TV Fool signal prediction report to look at, I'm still quite confident that signal levels 60 miles from the transmitters will likely call for a real antenna.
