The Digital Drift DD-LFC-RMC12-6927 is a high-performance 50-ohm leaky feeder (radiating) coaxial cable, designed for optimal signal distribution in confined environments such as mines and tunnels. With Low Smoke Zero Halogen (LSZH) fire-retardant properties, it ensures safety while delivering consistent signal performance. The cable operates in a wide frequency range from 690 MHz to 2700 MHz, making it ideal for supporting Wi-Fi at 2.4 GHz and other wireless communication needs.

Constructed with copper-clad aluminum wire, overlapping copper foil shielding, and a durable black LSZH jacket, this cable provides excellent electrical and mechanical performance. It offers low attenuation, stable coupling loss, and a bending radius suitable for challenging installation environments.

This cable complies with IEC fire and smoke safety standards and is ISO 9001, ISO 14001, and OHSAS 18001 certified, ensuring reliability and durability for demanding applications.

This cable is supplied in 500m cable roll tied to a pallet.
