Astrotek 30m CAT5e RJ45 Ethernet Network LAN Cable Grounded Shielded FTP Outdoor Patch Cord 24AWG-Cu 2xRJ45 STP PLUG PE Jacket This cable has special grounding as required by Ubiquiti™ such as the NanoStation range of products. It has: The standard 8-wire, straight-through LAN wiring. Special metal clad shielded RJ45 connectors. These connectors make ground contacts with the grounded RJ45 sockets on Ubiquiti devices and POE injectors. A Foil Shield surrounding the conductors, and electrically connected to the metal shields on the RJ45 connectors. This provides an electrical path from the circuit board of the Ubiquiti™ device, and the ground pin of the AC cord used with the POE injector. This path prevents voltage build-up during nearby electrical storms that can destroy the ethernet interface on the Ubiquiti™ device. A weatherproof, externally rated jacket.
