Overview of LMR 400 Coaxial Cable

Structure of LMR 400 Cable

• Conductor: Made from pure copper or silver-plated copper, the conductor ensures the best signal transmission with minimal signal loss.
• Dielectric Layer: Uses foam polyethylene (Foam PE), which helps reduce signal loss and increase stability when transmitting at high frequencies.
• Shielding Layer: Consists of an aluminum tape layer and a copper braid layer, helping to eliminate electromagnetic interference (EMI) and unwanted RF signals.
• Outer Jacket: Made from PVC or polyethylene, it is UV resistant, heat resistant, and waterproof, helping to protect the cable from environmental factors.

Key Technical Specifications

• Outer Diameter: 10.3 mm.
• Impedance: 50 Ohm, standard for RF applications.
• Operating Frequency Range: Up to 6 GHz.
• Signal Loss: Approximately 0.22 dB/m at 2.4 GHz frequency, ensuring high signal quality over long distances.
