Key Features
- Integrated Surge Protection: Combines power injection with robust surge mitigation to protect switches and indoor equipment from electrical damage.
- Gigabit Throughput: Fully compatible with 10/100/1000 Ethernet standards, ensuring no compromise on network data speeds.
- Broad Thermal Range: Built to operate reliably in extreme environments ranging from -40°C to 70°C.
- System Security: Designed to be used in conjunction with the MikroTik GESP unit for complete end-to-end protection, securing both the antenna mast and the ground-level network hardware.
- Easy Deployment: Compact design allows for simple installation below antenna masts or near rack-mounted equipment.
Note: For optimal performance, always ensure the device is securely connected to a proper grounding point (such as a rack, mast, or structure ground). While designed to absorb multiple surge events, it is recommended to inspect the unit following any significant electrical incidents.
