The GRD-RAD1 Radial Grounding System is an advanced, portable grounding solution designed for lightning protection systems, portable equipment, and temporary installations. Engineered for quick deployment and superior performance, this system is ideal for environments where traditional 8-ft ground rods are impractical, such as frozen or rocky soil.

Unlike standard ground rods, the GRD-RAD1 system achieves significantly lower ground resistance—62 ohms compared to 111 ohms in controlled tests*. The system includes three 25-ft radial ground cables, each equipped with five 12″ flexible grounding stakes, ensuring a secure and adaptable grounding layout.

Designed with military-grade reliability, this system is functionally similar to US Army grounding specifications, making it an industry-trusted grounding solution. Its modular configuration allows users to extend grounding up to 75 feet in loop, branched, or linear layouts, providing maximum adaptability for various field applications.

For added convenience, the GRD-RAD1 Radial Grounding System includes two 5-ft jumper cables, allowing seamless integration with facility or lightning protection system grounding lugs. The system is also compact and easy to transport, making it perfect for frequent relocation and reuse.

Whether used for temporary site installations, industrial facilities, or critical infrastructure, the GRD-RAD1 Radial Grounding System ensures optimal performance, reliability, and ease of use in challenging environments.
