Title: Radio receiver protection arrangement

Abstract: A receiver protection arrangement in which a voltage dependent on aerial voltage and a voltage dependent on aerial current are aggregated and applied to means responsive to a predetermined aggregate level to effectively short circuit the aerial lead. Additional means may be provided to dissipate energy in the input stage of a protected receiver to cause a reduced impedance to be reflected across the output of the protective arrangement.
