50 ohm leaky coaxial cable

Application Range:

      The leaky coaxial cable for coal mines is suitable for use as a transmission line for communication systems in mines, subways, underground tunnels, and underground facilities inside buildings in special environments where radio waves cannnot be directly transmitted or transmitted poorly. 

      This product has the dual functions of signal transmission line and antenna.

Operating characteristics:

  1. Working frequency: 1GHz and below

   2. Operating ambient temperature: -25°C ∼70°C

   3. Laying temperature: not lower than 0°C

   4. Bending radius: not less than 15 times the outer diameter of the cable.

 Advantages:

       We have the largest production capacity and advanced test device for leaky coaxial cable in China.

      This product has the characteristics of low attenuation, low VSWR and excellent water tightness, air tightness and flame retardancy.
