MikroTik GESP+POE-IN Passive PoE Injector – Professional Network Power Solution

MikroTik GESP+POE-IN is a passive PoE injector with built-in surge protection, designed for outdoor installations where antennas, access points, and switches are exposed to lightning strikes or static charge build-up. It is the right choice when mast-mounted network equipment needs both passive PoE power delivery and reliable surge protection in a single device.

The unit serves two critical functions simultaneously: it injects passive PoE power toward antennas or access points mounted above, while protecting downstream switches from voltage surges caused by atmospheric discharge or static accumulation. Paired with a GESP surge protector at the top end of the cable run, it creates a complete two-endpoint protection system — covering the full length of the cable and maximizing the safety of the entire outdoor installation.

GESP+POE-IN is positioned at the base of the mast or structure, protecting ground-level switches and powering equipment above. Combined with the GESP unit at antenna level, the entire cable run is protected. Mounting is straightforward using PVC zip ties, with no specialized tools required. Proper grounding of the supporting metal structure is essential for maximum surge protection effectiveness.

Recommended for mast and rooftop antenna installations, outdoor wireless networks in storm-prone areas, distributed ISP infrastructure, and any deployment where long cable runs connect elevated equipment to ground-level switches. A small upfront investment that eliminates the cost and downtime associated with surge-damaged network hardware.
