MikroTik GESP Gigabit Ethernet Surge Protector in IP67 waterproof enclosure

GESP is Gigabit Ethernet Surge Protector that can be used to protect the network from lightning or surge damages.

Here’s what a typical use-case would be like. You have a mast with some antennas. And some switches on the ground. Put the GESP surge protectors on each end. They come sealed inside a new and improved IP67 weatherproof enclosure. Your antennas are now safe during a lightning storm.

Don’t forget about the grounding wire! Secure it to the rackmount, mast, or any other structure that is connected to the ground. For maximum protection, you should use a surge protector on both ends of long cables.
