Leaky feeder cable/MSHA cables are used when normal radio communication is difficult or impossible in particular communication systems where a discrete antenna would not provide
Adequate coverage. A radiating cable functions not only as a transmission line but also as an antenna.

      Li-Bo SLYFYVZ-75-10polyethylene foaming bunchy outer conducter conductor radiating coaxial cables, which are based on international advanced standards, have very good electrical performances and can be widely used in the following applications:
Buildings, Mines, subways and tunnels
Travlers information stations/highway advisory radio
Uncovered area by antennas
Note: Fire-Retardency PE outer sheath can be availabe per customer's requirment.
