Abstract
An antipersonnel barrier system includes at least one concertina coil and a plurality of spaced support members. Each of the support members includes a base section and a vertical section. Each of the concertina coils is secured to the support members to provide a horizontally and vertically stabilized barrier. A length limiting cable is provided to limit the length of spacing between adjacent support members. The support members can include anchoring structure for securing the support members to a support surface. In one embodiment, the concertina coils include two small diameter base coils and a top coil positioned on the base coils.
