Antenna clamps
Protection down to the details from DEHN
When it comes to safeguarding buildings from the devastating effects of lightning, every detail matters. DEHN’s line of antenna clamps offers a critical layer of protection for SAT and antenna systems, ensuring they’re properly earthed and properly fitted into your overall external lightning protection system.
With over a century of expertise, DEHN continues to deliver solutions that protect buildings and the people and electrical equipment inside them.

Lightning can strike anytime – Is your building prepared?
Lightning is unpredictable and immensely powerful, releasing up to 300 million volts of energy in a single strike.
When a building lacks proper lightning protection, external elements like antennas, satellite dishes, and gutters become vulnerable entry points for lightning currents. This type of transient surge can lead to fires, structural damage, equipment failure, and even personal injury.
DEHN’s antenna clamps are a vital part of any external lightning protection system. Designed to provide consistent equipotential bonding and functional earthing, these components work as a part of the larger lightning protection concept to prevent dangerous touch voltages and ensure that lightning currents are safely discharged.
By integrating these clamps into your system, you can protect your building from the devastating effects of lightning.
Simple solutions for a powerful problem
Antenna clamps might be small, but their impact is significant. These specialized connectors ensure that antenna systems are properly bonded to the building’s lightning protection infrastructure, preventing dangerous electrical surges from spreading.
DEHN’s antenna clamps are engineered to meet the highest standards, including those set by the NFPA and other regulatory bodies. These clamps are lightning-current capable, versatile in application, and made from durable materials to ensure long-term reliability. Whether you’re retrofitting an older system or installing a new one, DEHN’s antenna clamps make it easy to achieve compliance and peace of mind.
