Abstract : A device for the protection of antennas against lightning and electromagnetic pulse consists of an electrically conducting rotor that is free to turn on a conducting shaft which is connected to the antenna. This combination is placed within an electric coil with one end connected to ground. The rotor is mounted eccentrically within the coil so that when a predetermined critical voltage on the antenna is exceeded electrical current flows through the rotor, and coil to ground via the air gap separating the rotor and coil, a magnetic field is set up in the coil which turns the rotor and reduces the air gap as the voltage is dissipated, after discharge of the surge, the rotor returns to its quiescent position.
