RADIAFLEX® radiating cables are “leaky feeder” coaxial cables designed to provide continuous RF coverage along the length of the cable. Instead of feeding a single antenna, the cable radiates signals through slots in the outer conductor, acting as a distributed antenna system (DAS) for tunnels, underground spaces, and large buildings.

Key Benefits

• Continuous RF coverage along the entire cable length
• Eliminates need for multiple antennas in confined spaces
• Supports multi-band wireless systems (2G, 3G, 4G, 5G and mission-critical radio)
• Reliable communication in challenging environments like tunnels and underground infrastructure
• Low signal loss and high durability for long deployments

Typical Specifications

These cables are designed to support multiple communication services simultaneously due to broadband capability.

Available Cable Sizes

Typical RADIAFLEX cable diameters:

Larger cables provide longer coverage distance and lower loss.

Frequency Range

Typical supported frequencies:

RADIAFLEX cables support all commercial and mission-critical services up to around 6 GHz.

Transmission Line Type

• Radiating coaxial transmission line (Leaky feeder cable)
• Corrugated outer conductor with precision slots to radiate RF energy
• Foam dielectric insulation
• 50-ohm impedance

Unlike standard coax cables, these function as a distributed antenna along the cable length.

Common Connector Types

Typical connectors used with RADIAFLEX systems:

• N-type connectors
• 7/16 DIN connectors
• 4.3-10 connectors
• EIA flange connectors (for large cables)

Connector families are designed to minimize PIM and maintain RF performance.

Typical Applications

RADIAFLEX cables are widely used in:

• Metro and railway tunnels
• Road tunnels
• Mines
• Underground stations
• Airports and large buildings
• Public safety communication systems

RADIAFLEX cables provide reliable connectivity in confined areas where traditional antennas cannot deliver consistent coverage.
