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.
