When using a radiating cable to provide radio signal coverage in tunnels, on underground railways, inside buildings, in mines
When using a radiating cable to provide radio signal coverage in tunnels, on underground railways, inside buildings, in mines, etc. the cable must be extremely reliable and designed to withstand the strain of the installation environment.
To maintain the cable's excellent electrical characteristics in humid conditions, NK Communications provides its radiating cables with a specially designed feature: a thin solid polyethylene layer on top of the foam insulation, which constitutes an effective seal against moisture. This special insulation design improves the service life and reliability of radiating cables.
Cables to be installed in confined spaces must meet strict specifications for fire-retardancy, smoke generation and toxic emissions. The cable jacketing can be made of flame-retardant and halogen-free materials, according to the customer's requirements. To further improve the cable's fire-retardancy, a special mica barrier tape between the outer conductor and outer jacket is available as an option.
NK Communications has designed its RFX range of radiating cables by making use of NK Communications know-how in developing antenna feeder cables for mobile network base stations. A good example of this know-how is the unique cable insulation process in which nitrogen is used as an expander gas. The high foaming degree of the insulation foam and accurately machined slots along the outer conductor, guarantee minimal longitudinal attenuation and coupling loss.
General Characteristics
- Low attenuation and coupling loss.
- Good crush-proof characteristics.
- Flame-retardant and halogen-free jacketing available.
- Messenger wire option for easy installation.
- Ozone-friendly nitrogen gas-foamed polyethylene.
- Polyethylene skin foam-skin insulation to prevent
moisture penetration.

There are two types of outer conductors available:
- The welded corrugated copper conductor is mostly used when flexibility and good mechanical durability are required.
- The overlapped non-corrugated copper band is used in less severe ambient conditions.
