The antenna is attached to A, and a pipe in the ground is attached to E. The television signal can go from A to B but not from B to C or from C to D.
The antenna is attached to A, and a pipe in the ground is attached to E. The television signal can go from A to B but not from B to C or from C to D. However, when the high voltage of lightning hits, it can easily go through the air from B to C and from C to D and E.
