Since its launch in 1972, RADIAFLEX® has constantly evolved to maintain its status as a leading solution for in-tunnel communications. Let’s look at why it is trusted by organizations worldwide to deliver reliable, high-quality wireless communications.
RADIAFLEX radiating cables take contoured wireless coverage everywhere the cable is installed to eliminate the need for traditional antennas in confined spaces. After five decades, these innovative broadband cables are still the world’s leading solution for in-tunnel wireless connectivity, and are delivering uninterrupted communications in some of the world’s most high-profile and challenging tunnels. And we continue to lead the way with future-ready solutions that take 5G underground.
RADIAFLEX cables deliver everything needed to improve in-tunnel wireless communications today and tomorrow.
RADIAFLEX cables support multiple operators, frequency bands and technologies so they can deliver all mission-critical and commercial wireless services in tunnels.




RADIAFLEX cables support all services up to 6 GHz and provide ultra-wideband frequency coverage to 3.8 GHz with no stopbands so it’s easy to take advantage of new spectrum, upgrade to 5G underground and support new services.
Combining vertically polarized and horizontally polarized RADIAFLEX cables creates near-perfect MIMO conditions in tunnels and set a world record for in-tunnel download speeds in 2018, reaching 560 Mb/s.
RADIAFLEX cables ensure low longitudinal and coupling losses, can be tailored for maximum performance over longer cable runs, and are optimized to deliver mission-critical communications with complete reliability.
RADIAFLEX cables meet all major international flame and fire-retardance standards and achieved the top Construction Products Regulation (CPR) rating of B2ca with a d0 droplets rating.

A complete range of robust, high-performance RADIAFLEX cable connectors, clamps, and cable ties ensures installations are efficient and cost-effective.

France | 2 Phases, 2021-2030
RFS RADIAFLEX® radiating cables have been selected to deploy a 2x2 MIMO private LTE network. The cables fulfilled all projects needs with regard to future-readiness and the highest fire safety requirements according to the European Construction Product Regulation (CPR).
Norway | 2019-2020
The Follobanen project features a unique 4x4 MIMO solution deployed in Norway, which set the world record for in-tunnel download speeds in 2018. RFS’ vertically polarized RAY and horizontally polarized RLK product families take advantage of unique cross-polarization effects to optimize MIMO conditions in tunnels.


Brazil | 2020

After the World Championship and Olympics, best-in-class RADIAFLEX® is selected again for Rio’s latest 4G multi-band, multi-operator in-tunnel wireless network deployments.
USA | 2019-2024
High capacity wireless systems in multiple subway and railway tunnels in dense urban New York City area.
Singapore | 2019-2024

Extension of world-class public transportation system relying again on longterm first choice RADIAFLEX.
RFS in-tunnel solutions are deployed in some of the most iconic tunnels in the world — old and new. Here’s a summary of key projects* that leverage our solutions, in-tunnel & selected in-building.
Over the last 5 decades, RADIAFLEX has become the go-to solution for mission-critical and commercial connectivity in underground rail settings.
Comprehensive contoured coverage, adaptability to new standards, and RFS’s ‘built to last’ promise means it is now deployed in 51.34% of metro and subway systems across the globe
