Siemens IWLAN RCoax cable PE 1/2'', 5GHz short distance Part number 6XV1875-2D

This is a leaked radiating coaxial cable for industrial wireless LAN applications operating in the 5 GHz band over short distances. It functions as an antenna along its length, distributing radio signal continuously rather than from a single point, which supports reliable wireless coverage in areas with obstructions or restricted line of sight. Typical applications include tunnels, conveyor systems and other confined industrial environments where standard antennas would give inconsistent coverage.
