Faraday Cage Solutions
The cornerstone of Pepro’s patented enclosure technology is the principal of the Faraday Cage, which offers protection from lightning strikes, Electromagnetic Pulse (EMP), Electromagnetic Interference (EMI), and Radio Frequency Interference (RFI). The use of Pepro’s technology also lessens the effects of Passive Inter-modulation (PIM) when all equipment is installed and maintained properly. All technology has been thoroughly tested by independent sources to prove PEPRO manufactures the best-performing Faraday Cage-protected enclosures and shelters on the market. All tests are done to Mil-Spec requirements by independent third-party testing facilities.
Lightning Technologies, Inc. of Pittsfield, Massachusetts reports:
- A direct lightning test put 1 Million Volts and 80,000 Amps directly onto the enclosure with only 10 microjoules penetrating the enclosure’s interior.
- Verified a 40db shielding effectiveness rating for stray EMI.
- Most Recent Tests: February 2011
Lightning and Electromagnetic Effects Testing
Our engineering staff is committed to the design and testing of methods to eliminate the effects of lightning and electromagnetic interference. With a properly designed structure, your sensitive equipment can survive and continue to perform even in the midst of a lightning event. Watch now to learn more!
Faraday Cage Ground Pads & Ballast Plate System
Industry-leading Ufer grounding pads, also known as Ufer grounds, are included on many PEPRO structures and shelters. They are a standard option on Walk-In Shelters larger than 6'x6', Micro Sites, Nano Sites, Platform Towers, and more. Every shelter and cabinet with an attached tower includes Ufer ground pads that complete the faraday cage system allowing towers to take the brunt of a lightning strike without compromising the tower, structure, or any equipment functionality. Aligning with our low environmental impact installations, these pads serve as a base for towers, require minimal preparation for deployment, and leave no permanent effects after deployment.
Within the concrete pads there are nearly 16 feet of iron rebar that not only reinforce each pad but also act as a grounding electrode to complete the faraday cage system allowing any electrostatic charges to be discharged safely into the ground away from equipment or shelters. Ufer grounding pads were invented and named after American scientist Herbert Ufer in 1942 during World War II. Ufer grounds were invented as an alternative to copper grounding rods. Ufer grounds are officially known as "Concrete Encased Electrodes" by the National Electrical Code.

While there is an incredible amount of research and technology behind our patents, a Faraday Cage (shield) can be most simply described as an enclosure created by conducting materials that block external electric fields (both static and non-static).
This shielding actively protects electronic equipment from electrostatic discharges, radio interference, over-voltage from a lightning strike, and safeguards the interior for an enclosure or shelter from outside electromagnetic radiation. Faraday Cage technology is a nearly infallible way to protect you mission-critical telecommunications equipment and other electronic devices.
