How long does it take for the tv signal to get to the tv mast to the tv set?

The time it takes for a TV signal to travel from the TV mast to the TV set is typically very short, usually just a fraction of a second. Radio waves, which carry the signal, travel at the speed of light, approximately 299,792 kilometers per second (186,282 miles per second). Therefore, even over considerable distances, the delay is often imperceptible to viewers, usually in the range of milliseconds.
