Professional Industry Advantages
-
High-Flexibility Stranded Core: Unlike the solid conductor used in RG142, the RG400 utilizes a 19-strand silver-plated copper core. This design provides significantly better flexibility and resistance to mechanical fatigue, making it ideal for applications involving repeated movement or installation in tight aerospace compartments.
-
Superior Double-Shielding Architecture: Featuring two successive layers of high-density silver-plated copper braiding, this cable offers extreme shielding effectiveness (greater than 100 dB). It effectively eliminates Radio Frequency Interference (RFI) and ensures signal integrity in high-density electronic environments.
-
Extended Frequency Range: Specifically optimized for ultra-wideband performance up to 11 Gigahertz. This makes it a future-proof solution for next-generation radar, microwave testing, and satellite communication systems.
-
Exceptional Thermal & Chemical Stability: The combination of high-grade Polytetrafluoroethylene (PTFE) and Fluorinated Ethylene Propylene (FEP) ensures the cable remains non-combustible and chemically inert. It maintains stable electrical characteristics from -55 degrees Celsius up to constant high heat of +200 degrees Celsius.
-
Military-Grade High-Voltage Safety: Rated for 1900 Volts, this cable provides a substantial safety margin for high-power transmitters and pulse-modulated signal paths in mission-critical defense and medical systems.
