RG-223 Cable

Description

RG-223 is a premium, double-shielded version of the standard RG-58, designed for 50 Ohm systems that demand superior shielding effectiveness. Manufactured to meet strict MIL-C-17 military specifications, it is optimized for high-performance RF environments where signal leakage or external noise could compromise system integrity. The cable features a solid silver-plated copper center conductor, which provides exceptional conductivity and signal stability compared to standard bare copper or alloy cores.

The defining feature of RG-223 is its dual-layer silver-plated copper braid. This double-shielding architecture provides significantly higher RF isolation (typically >60 dB) than single-shielded cables, making it ideal for use in dense electronic racks and high-interference areas. The silver plating on both the conductor and the shields utilizes the “skin effect” to enhance high-frequency performance and provide superior resistance to corrosion. Encased in a non-contaminating Black PVC jacket, it is built to withstand environmental degradation and maintain stable electrical properties for years. It is most commonly terminated with BNC, N-Type, or TNC connectors.

Key Technical Advantages

• Superior Double Shielding: Two layers of silver-plated copper braid offer exceptional protection against electromagnetic interference (EMI) and minimize signal cross-talk.

• Silver-Plated Signal Path: Silver plating on the internal conductor and both shields ensures low resistance and prevents oxidation, maintaining performance over time.

• High-Frequency Precision: Optimized for performance into the GHz range, providing a flat response and low VSWR for critical RF infrastructure.

• Non-Contaminating Jacket: The Type IIA PVC jacket prevents plasticizer migration into the dielectric, ensuring the cable’s electrical properties remain stable over a long operational life.

• Exceptional Signal Isolation: The double-shielded design ensures minimal signal egress, protecting sensitive adjacent equipment from interference.
