ZCG Scalar's 7890-100 also known as RU400 low-loss coaxial cable is engineered for high-performance RF signal transmission across a wide frequency range from DC to 5.8 GHz. Featuring a foam polyethylene dielectric and copper clad aluminium conductor, this 50 Ohm cable is designed to minimise attenuation and preserve signal integrity, making it ideal for high-frequency and long-run applications in demanding environments. Equivalent in performance to leading 400-series coaxial cables, the RU400 provides excellent electrical stability and low insertion loss, supporting reliable operation across 4G/5G networks, Wi-Fi systems, IoT infrastructure, broadcast installations, and general RF communications. Its precision construction ensures consistent impedance and effective shielding, reducing signal loss and interference in critical systems. Supplied as a 100 metre roll, the 7890-100 offers a practical solution for small-to-medium installations or single-run applications where flexibility and ease of handling are required. It is well suited to installers and integrators needing high-quality coaxial cable without the bulk of larger reels. Built for durability, the RU400 performs reliably in outdoor and industrial conditions, maintaining electrical performance under environmental stress and during installation. Combining low-loss characteristics, wide frequency capability, and robust construction, the 7890-100 RU400 coaxial cable from ZCG Scalar is a dependable choice for professional RF systems requiring consistent, high-quality signal transmission.
