Abstract : The patent describes a wideband radar receiver protective apparatus. A glass envelope in the shape of an elongated doughnut is used to provide a low pressure glow discharge in a coaxial configuration. The coaxial configuration consists of two separated sections of coaxial transmission line with the glass envelope interposed therebetween. The coaxial configuration interconnects a transmitter and the receiver to be protected. Generation of the glow plasma is controlled by means of a power source separate from the transmitter. The length of the glow region determines the amount of attentuation. The glass envelope includes an inert gas in combination with a barium getter to preserve the purity of the gas almost indefinitely.
