TELEGÄRTNER N-Type Surge Arrester, Plug to Jack, IP67, Lambda/4 Short Circuit, 380-512 MHz TETRA (J01028A0051)

Protect sensitive TETRA base station equipment from lightning-induced surges and transient overvoltages with the TELEGÄRTNER N-Type Surge Arrester. This in-line protector features a Lambda/4 short-circuit design, effectively shunting surge currents to ground while maintaining low insertion loss for reliable signal transmission in the 380-512 MHz band.

Who is it for

Engineers and technicians deploying TETRA mobile radio systems, base stations, and outdoor antenna installations. Ideal for environments where equipment is exposed to lightning strikes or power surges, requiring robust protection without compromising RF performance.

Tips

For optimal protection, install the surge arrester as close as possible to the equipment being protected, and ensure proper grounding of the arrester body. The IP67 rating allows outdoor mounting, but avoid submersion in water for extended periods. Verify that the frequency range matches your TETRA system's operating band before installation.
