Description
50 Ohm Flexible Coaxial Cable | PVC Jacket | Foamed Polyethylene Dielectric
The ROSNOL RNL-300 is a 50 Ohm low-loss coaxial cable engineered for RF and microwave systems operating from DC to 8 GHz. It features a solid bare copper inner conductor (∅1.78 mm / 0.0701 in) and a foamed polyethylene dielectric (∅4.84 mm / 0.1906 in), shielded by aluminum tape and a tinned copper braid (∅5.7 mm / 0.2244 in). The PVC jacket (∅7.6 mm / 0.2992 in) ensures robust protection and flexibility. The cable supports a static bending radius of 22.2 mm (0.8740 in) and dynamic radius of 76.2 mm (3.000 in), withstanding up to 2 kV AC at sea level.Electrical specifications include 77.0 pF/m capacitance, 85% signal velocity, and 3.92 ns/m signal delay. Typical attenuation ranges from 0.08 dB/m at 0.15 GHz to 0.65 dB/m at 8 GHz, with maximum CW power handling of 920 W at lower frequencies. The RNL-300 is fully compatible with Times Microwave’s LMR-300, providing a high-performance and cost-effective alternative for equivalent system designs.
ROSNOL’s cable solutions are precision-engineered to meet the rigorous demands of RF and microwave transmission systems. Manufactured under ISO 9001-certified processes, ROSNOL cables deliver consistent high quality and performance at competitive pricing, making them a reliable alternative to products from leading European and American brands. All ROSNOL cables are fully compliant with global environmental and safety regulations, including RoHS and REACH. Customization services for materials, shielding, and mechanical design are available to support specialized application requirements.
