EZ Digital Antenna

[jfarley]

A product EZ Digital Antenna is being advertised on the internet to be able to receive signals generated from cable channels. They say that cable companies are required to produce an on air signal as well as the cable signal but now EZ Digital is able to access this on air signal thereby allowing a user to get cable as well as broadcast channels free.
Is this legitimate?
Is it legal?

Cable only channels are not available over the air regardless of the antenna.
Maybe they think don't realize some channels on cable are free over the air channels.
