Lightning protection apparatus for antenna-coupled RF equipment is provided. A one quarter wavelength shorting stub bandpass filter shunts the RF equipment and a distributed capacitance, high voltage coaxial capacitor is serially coupled between the equipment and antenna. The shorting stub is tuned to one quarter wavelength of the RF equipment operating frequency. The series capacitor passes frequencies at or above the operating frequency of the RF equipment.
L'invention est un dispositif de protection contre la foudre pour un matériel RF couplé à une antenne. Un filtre passe-bande à bras de court-circuitage met le matériel RF en dérivation et un condensateur coaxial haute tension à capacité répartie est monté en série entre le matériel et l'antenne. Le bras de court-circuitage est accordé à un quart de la longueur d'onde de travail du matériel RF. Le condensateur série laisse passer les signaux dont les fréquences sont égales ou supérieures à la fréquence de travail du matériel.
