Abstract
Abstract An electronic bird repellent system utilizes a ''''sandwich like'''' transmission line assembly for conducting high voltage about an area to be protected. The transmission line comprises a top and bottom conductive foil separated by a suitable insulating member, for providing support and separation. The system includes high voltage protection circuitry to prevent prolonged shock hazard and voltage monitoring circuitry to provide an indication determinative of an open circuit in said transmission line.
