SERIES 3400

Standard quarter-wave

SUHNER quarter-wave lightning protectors offer the best lightning protection available in the market, as they form a short for surge signals. They have been established as a worldwide industry standard by HUBER+SUHNER as the original manufacturer. The products are maintenance-free and feature the best protection performance with both the highest surge-current-handling capability and the lowest residual pulse amplitude. Also, their RF performance is superior to other designs, including passive intermodulation.

SUHNER lightning protectors series 3400 offer a large variety of products and can be adapted to any application. Besides connectorisation and mounting principle, the frequency range has to be selected properly due to their generally limited bandwidth.
