The 8121-300 RU400-75 is a high-performance low loss 75 Ohm coaxial cable supplied on a 300 metre roll, engineered for dependable RF transmission from DC to 2.5 GHz. Designed for professional broadcast, telecommunications and RF distribution systems, it delivers stable signal integrity across demanding commercial installations.
The cable construction features a solid copper centre conductor for excellent conductivity, a foam PE dielectric to minimise attenuation, bonded aluminium tape shielding, and a tinned copper braid for enhanced screening effectiveness. This layered shielding design reduces interference and supports consistent impedance performance. The outer black PE jacket provides durability and environmental resistance, making it suitable for both indoor and outdoor use.
