The ATL400 Low-Loss Coaxial Cable – LMR400-Type Alternative – Per Foot is a professional-grade coaxial cable built for demanding two-way radio environments. Highlights include lMR400-Type Performance and outstanding Signal Quality.
Key Features
- LMR400-Type Performance: A direct alternative to LMR400 — same if not better electrical performance including attenuation, impedance, and velocity ratio.
- Outstanding Signal Quality: Engineered for minimal signal loss with >90 dB screening factor from 1–1,000 MHz, ensuring reliable and efficient transmission.
- 20-Year Outdoor Service Rating: UV-resistant polyethylene jacket designed for long-term outdoor installations without degradation.
- Solid CCA Center Conductor: Copper-clad aluminum construction balances conductivity and weight for efficient signal delivery.
- Dual-Layer Shielding: Bonded aluminium foil + tinned copper braid provides >90 dB screening factor, minimizing interference and signal leakage.
- Wide Temperature Range: Rated -40°C to +85°C for reliable performance in demanding outdoor and in-vehicle environments.
