LT-LEAKY-1/2L-LSZH

Leaky1/2” Coaxial Cable

The LT-LEAKY-1/2L-LSZH is a high-performance leaky coaxial cable designed to provide reliable RF signal distribution in areas where conventional antenna systems are ineffective. Engineered with a low-smoke, zero-halogen (LSZH) jacket, this cable is ideal for environments that demand strict fire safety standards such as tunnels, underground facilities, buildings, and confined spaces. Its leaky (radiating) design enables consistent wireless coverage across the cable’s length, making it a dependable solution for in-building DAS (Distributed Antenna Systems),public safety communication, and transportation systems.
