Introduction to LMR 400 coaxial cable

Structure of LMR 400 cable

• Conductor: The cable core is made of pure copper or silver-plated copper, ensuring good conductivity and minimizing signal loss.
• Dielectric Layer: Uses foam polyethylene (Foam PE), which has excellent dielectric properties and minimizes signal loss at high frequencies.
• Shielding Layer: Consists of an aluminum tape layer and a copper braid layer, which helps protect the signal from electromagnetic interference (EMI) and unwanted radio frequency (RF) noise.
• Outer Jacket: Made from PVC or PE material, which is resistant to weather, UV rays, and other environmental factors.

Key Specifications

• Outer Diameter: 10.3 mm.
• Impedance: 50 Ohm.
• Maximum Operating Frequency: Up to 6 GHz.
• Low Signal Loss: Approximately 0.22 dB/m at 2.4 GHz.
