Do TV/ Radio Aerial Cables Carry Current? A TV aerial will capture radio-waves that are in the air and transfer them onto the coax cable that feeds your TV positions. The“signal” on a cable is in fact alternating current electricity, which is of a much, much higher frequency than that of your mains electrical supply.

Then, is it safe to cut through a TV aerial cable?

Usually a TV antenna cable (called coaxial cable or just coax) carries only low voltages that are not dangerous to humans. For this reason it's a good idea to use insulated wire cutters when cutting a coax cable that is connected in any way to equipment.
