Lighting protection apparatus for RF equipment and the like

摘要

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.
