Ultimate LMR-600-DB Direct Burial Low Loss Coaxial Cable
LMR-600-DB (Direct Burial) low loss coaxial cable is the ultimate solution for long-run RF applications exposed to extreme moisture, continuous water immersion, or direct underground burial. Featuring a flooded, watertight dielectric and a rugged black UV-resistant PE jacket, it delivers the superior, ultra-low loss performance of LMR-600 without the risk of moisture ingress and subsequent signal degradation.
100% Watertight Protection (DB – Direct Burial): The cable’s dielectric core is flooded with a proprietary sealing compound. This completely blocks moisture migration, ensuring consistent impedance and signal clarity even when submerged or buried underground.
Rugged PE Jacket: Features a thick, UV-resistant Polyethylene jacket that withstands abrasion, temperature extremes -40 C to +85 C, and degradation from sun exposure, roots, and soil chemicals.

Ideal Applications
- Direct Burial: Running cable underground between buildings, towers, or remote antennas.
- Wet Environments: Use in conduits prone to flooding, near shorelines, or areas with high water tables.
- Tower Bases: Jumper runs in junction boxes or vault installations where moisture is unavoidable.
- WISP / Point-to-Point Links: Critical low-loss links that must be run directly beneath sidewalks or roads.
- Marine & Coastal: Installations where salt spray and high humidity are constant threats.
