ZCG Scalar’s 7890-300 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 conductor, this 50 Ohm cable is designed to minimise attenuation and maintain signal integrity over long cable runs, making it ideal for demanding telecommunications and wireless applications.
Equivalent in performance to leading 400-series coaxial cables, the RU400 delivers excellent electrical stability and low insertion loss, supporting reliable operation in systems such as 4G/5G infrastructure, Wi-Fi networks, IoT deployments, broadcast installations, and general RF communications. Its construction ensures consistent impedance and shielding effectiveness, reducing signal degradation in high-frequency environments.

Supplied as a 300 metre roll, the 7890-300 provides flexibility for medium-to-large scale installations, allowing multiple cable runs or staged deployment from a single reel. This makes it well suited to contractors, system integrators, and infrastructure projects requiring dependable bulk cable supply. Shorter rolls of 100m – see 7890-100 – are available.
Built for durability in harsh outdoor and industrial conditions, the RU400 maintains performance under environmental stress, including temperature variation and physical handling during installation.
Combining low-loss performance, wide frequency capability, and robust construction, the 7890-300 RU400 coaxial cable from ZCG Scalar is a reliable solution for professional RF systems requiring consistent signal quality over extended distances.
