The L-1011-9 is a 228.6mm CHO-STRAP? insulated Ground Strap. It is flexible, double-insulated laminates of copper (inside) and polyester film (outside), with punched and tinned ends to facilitate termination. They provide low-impedance ground paths at RF frequencies, thereby reducing radiated EMI problems caused by ordinary wire grounds. They are generally more cost-effective than braided ground straps.
