FIELD: radio engineering; radio receivers and wire communication equipment.
SUBSTANCE: novelty is that proposed device incorporating high-voltage arrester, lead for connecting antenna or cable line, low-voltage arrester, lead for connecting input circuits of communication equipment, and posistor inserted between anodes of high-voltage and low-voltage arresters has cathodes of its high- and low-voltage arresters integrated and connected to ground.
EFFECT: simplified design, ability of repeatable operation.
