The invention relates to a lightning arrester device for exterior lightning protection in buildings, containers, tents and similar objects comprising at least one collector device and at least one lightning arrester arrangement which is connected to the collector device and leads to an earthing system and is connected there. According to the invention, one or more conductor loops are formed outside the object to be protected for locally reducing the lightning-related magnetic field in the area surrounding the lightning arrester arrangement in such a way that a magnetic field-reduced protection area is produced in the object, wherein the dimensions of the conductor loops determine the size of the protection area and at least sections of the conductor loops are arranged in the vicinity of the lightning arrester arrangement, so that, in the event of a lightning strike, a current iind is induced in the respective loop, which current generates a magnetic flux Bind which counteracts the magnetic flux Blightning in the lightning arrester arrangement and reduces said magnetic flux to a value Bred.
