Gold-Plated Copper Alloy Wire for Antenna and RF Signal Lines is engineered to provide superior electrical conductivity, minimal signal attenuation, and outstanding corrosion resistance-critical properties for reliable RF and antenna performance. With a high-conductivity copper alloy core and precisely applied gold plating, this wire ensures stable impedance, excellent high-frequency response, and extended durability even in harsh environments.
It is the optimal solution for high-frequency transmission lines, antenna feeders, and precision RF communication systems requiring consistent signal integrity.
Gold-plated surface minimizes insertion loss and enhances conductivity at high frequencies
High-conductivity copper alloy core ensures stable transmission performance
Smooth, bright finish improves solderability and RF connector bonding
Excellent corrosion resistance and mechanical flexibility for outdoor and aerospace use
Customizable diameter, plating thickness, and strand configuration for RF-specific applications
Antenna feeders and transmission lines for telecommunications and broadcasting
RF signal interconnects in wireless communication devices
Aerospace and satellite communication systems
High-frequency instrumentation and testing equipment
Medical imaging and diagnostic RF wiring
