Abstract: A lightning protection device (25) for an antenna receiver, includes a shield (40, 70) for a coaxial cable (35, 65) connected to the antenna, and a high-pass filter mounted in series relative to the shield and capable of limiting the low-frequency power flowing in the coaxial cable, including a capacitor (30, 50, 55) and an inductor lower than 1 ohm at the lowest frequency used by the receiver, the capacitor including at least one layer of a conductive material embedded in a printed circuit. In some embodiments, the capacitor is made of a printed circuit (30) including at least two floor plans (50, 55), each of which is connected to the ground of a connector (80, 85) of the coaxial cable. The printed circuit may e.g. include at least one layer of a highly pervious material sandwiched between two layers of a conductive material.
