Modern mobile radio technologies include remote radio technology where the HF amplifiers are installed in a separate housing next to the antennas.

Risk of injection
If supply lines are installed in parallel to the mast, there is the risk that surges are injected into these lines. The same applies to the antenna lines. To reduce injection of surges to an acceptable level, the supply line leaving the base station and the supply line at the amplifier near the antenna are protected by installing adequate lightning current and surge arresters.
Modular and coordinated single-pole lightning current arrester for protecting the power supply in d.c. applications. Mains follow currents are already prevented as they develop.
