Our TRAD® and NuTrac® radiating cables provide RF coverage in difficult-to-cover structures. Examples include rail and transit tunnels, underground mines, subways, metal-hulled ships, offshore oil rigs, nuclear power plants and buildings with metal supporting structures. Radiating cables can carry multiple frequencies on a single cable, and function as a single broadband antenna. The radio frequency signals are fed between the transmitter and antenna while a controlled amount of energy is leaked into the surrounding environment providing the necessary RF coverage.

NU-TRAC®

The Nu-Trac® radiating cables address applications where longer cable runs are required. Typical applications are long road tunnels, metros, and subway systems. The Nu-Trac series of cables are larger cables that offer lower down-line signal attenuation while still providing adequate RF coverage within the surrounding environment. This delicate balance of attenuation and coupling loss is achieved by the isolated overlapping shields that are separated by a thin polyethylene interlayer. The coupling mechanism between the inner and outer shields provides a controlled RF coverage.

TRC-1250-PE

 Nu-Trac®-1250 is a large-diameter radiating cable engineered for extended runs in tunnels, metros, and subways. With its dual-shield design and polyethylene interlayer, it ensures low attenuation and consistent RF coverage. The cable’s robust build and optimized coupling make it ideal for high-reliability indoor communication in challenging, enclosed environments.

TRC-1250-FR

 TRC-1250-FR is a Nu‑Trac® flame-retardant radiating cable designed for long indoor runs in metros, tunnels, and transit systems. Featuring a low-smoke, non-halogen polyolefin jacket and dual-shield construction, it ensures minimal signal attenuation and controlled RF coverage. Its robust 43 mm diameter and 50 Ω impedance make it ideal for high-performance, mission-critical RF communication.

T-RAD®

The T-RAD® series of flexible, low-loss cables is a cost-effective solution where point source antennas are not practical. T-RAD cables utilize a continuous single slot design by bonding a metalized shield to the low-loss foamed polyethylene core. This foamed core/shield design yields a very flexible, lightweight cable perfect for easy installation. The slot opening provides a balance between downline signal attenuation and coupling loss. Its broadband-friendly design allows it to be used from lower frequency AM/FM radio rebroadcast through the higher frequency 802.11 WLAN applications.

T-RAD-400-FR

 T-RAD-400-FR is a flame-retardant, low-loss radiating cable designed for confined RF environments requiring enhanced fire safety. Its bonded shield and foamed core construction provide exceptional flexibility, lightweight handling, and consistent broadband coverage. Ideal for indoor applications, it supports frequencies from AM/FM radio to 802.11 WLAN, delivering safe, reliable performance in complex installations.

T-RAD-900-FR

 T-RAD®-900 Standard cable, FRPE jacket

T-RAD-900-PVC

 T-RAD-900-PVC is a high-capacity flexible radiating cable designed for indoor broadband RF systems. Featuring a foamed polyethylene core and bonded shield, it ensures low signal loss and wide-area coverage. The PVC jacket offers added protection for indoor routing, making it ideal for AM/FM rebroadcast, WLAN, and other wireless communication needs in complex building layouts.

T-RAD-600-DB

 T-RAD-600-DB is a durable, direct burial-rated flexible radiating cable built for underground RF distribution. Its bonded shield and foamed core enable low-loss, broadband signal performance from AM/FM to WLAN. With a rugged jacket for moisture resistance, it’s ideal for challenging outdoor or underground installations requiring long-lasting, reliable connectivity.

T-RAD-600-FR-MSHA

 T-RAD-600-FR-MSHA is a flame-retardant, MSHA-certified flexible radiating cable designed for mining and tunnel applications. Its low-loss foamed core and continuous slot design ensure consistent RF coverage in confined environments. Lightweight and highly flexible, it supports broadband signals from AM/FM to WLAN, delivering safe and reliable performance in harsh underground conditions.

T-RAD-600-PVC

 T-RAD-600-PVC is a high-performance, flexible radiating cable ideal for confined or complex RF environments. With a foamed polyethylene core and bonded shield, it offers low signal loss and uniform coverage. The PVC jacket adds durability for indoor use, supporting a wide frequency range from AM/FM rebroadcast to 802.11 WLAN wireless applications.
