‌LMR400 Low Loss Coaxial Cable: High-Performance RF Solution for Long-Distance Signal Transmission‌

LMR400 is a premium flexible coaxial cable designed for demanding RF and wireless communication systems. Known for its exceptional signal integrity and durability, it has become the industry standard for applications requiring low attenuation and reliable performance.

‌Key Advantages of LMR400 Coaxial Cable‌

‌1.Ultra-Low Signal Loss‌

(1) ‌Attenuation:‌ 3.9 dB/100ft @ 2 GHz (Superior to RG8/U and RG213)

(2) ‌Velocity of Propagation:‌ 85% (Efficient signal transmission over extended distances).

2.Enhanced Shielding & EMI Protection‌

(1) ‌Tri-Shield Design:‌

1) Inner Conductor: Bare copper (Solid/Stranded options)

2) Dielectric: Foam polyethylene (Low capacitance)

3) Shielding: Dual-layer aluminum foil + 95% braided copper

(2) ‌Shielding Effectiveness:‌ >90 dB (Ideal for high-interference environments).

3.Outdoor Durability‌

(1) ‌Jacket Material:‌ UV-resistant black polyethylene (PE) or PVC.

(2) ‌Temperature Range:‌ -55°C to +85°C (Withstands extreme weather conditions).

(3) ‌Bend Radius:‌ 1.0 inch (Dynamic flexibility for easy installation).

‌4.Cost-Effective Alternative‌

(1) Comparable performance to semi-rigid cables (e.g., Heliax) at 40% lower cost.
