LMR-400-DB Watertight Coaxial Cable

Rugged LMR-400-DB Dual-Jacket Direct Burial Coaxial Cable

LMR-400-DB is the gold standard for outdoor and underground RF communication. While maintaining the industry-leading low-loss characteristics of the standard LMR-400, the “DB” (Direct Burial) variant adds a critical layer of protection: a watertight sealing compound surrounding the braid. This ensures that even if the outer jacket is compromised, moisture cannot migrate along the cable, protecting your equipment and signal integrity for up to 20+ years.

Features

• Watertight Construction: Features a specialized inert flooding compound that prevents water ingress, making it ideal for direct burial or high-humidity environments.

• Superior Low Loss: Outperforms standard RG-8 and RG-213 cables with significantly lower attenuation, even at higher frequencies (up to 6 GHz).

• High RF Shielding: Double-shielded design (Aluminum Tape + Tinned Copper Braid) provides >90 dB of shielding effectiveness—perfect for EMI-congested areas.

• UV Resistant: Durable Black Polyethylene (PE) jacket designed to withstand harsh Middle Eastern sunlight and extreme temperatures.

• Flexibility: 1-inch (25.4 mm) installation bend radius allows for easy routing in tight spaces compared to corrugated hard-line cables.
