Protection of LTE systems Highest reliability, lowest risk, fast site approval, reduced maintenance cost The perfect coaxial lightning protector for LTE installations is the one which archives best protection results while at the same time it is not degrading the RF systems performance at all. Starting with the RF performance this means that it shall accomplish the full LTE bandwidth (690 to 2690 MHz) with highest possible return loss (RL). LTE is a high power, multicarrier application which demands for lowest passive intermodulation products distortion. Certainly the lightning protection parameters shall be of the highest standards in order to increase system reliability, lower risk and reduce maintenance cost. HUBER+SUHNER set industry standard At the advent of digital mobile communications HUBER+SUHNER set the industry standard in coaxial lightning protection with its quarter-wave shorting stub lightning protectors series 3400 the patented GDT hybrid protectors series 3409 and the self-extinguishing GDT protectors «Semper». HUBER+SUHNER offers a portfolio of lightning protectors for the LTE application which represents the state of the art in this domain. RL PIM Surge current Residual energy ≥ 28 dB from 690 to 2690 MHz ≤ –160 dBc up to 100 kA 11 µJ Quarter-wave shorting stub technology For all applications which do not apply DC power on the feeder cable the series 3400 (quarter-wave shorting stub principle) with its excellent lightning protection parameters represents the best possible technology.
