What is LMR-195-DB Cable?

The LMR-195-DB cable is a robust, direct burial 50-ohm coaxial cable designed for outdoor and underground applications where water resistance and long-term reliability are critical. Its unique water-blocking technology ensures the cable remains protected, even if the jacket is compromised, preventing moisture intrusion and minimizing signal loss over time. The cable is built with a solid copper conductor, nitrogen-injected foam polyethylene dielectric, double shielding, and a UV-resistant polyethylene jacket for extended outdoor service life.​

Key Features

• Water-blocking layer for enhanced moisture resistance​

• Double-shielded: aluminum foil and tinned copper braid​

• Attenuation: 11.1 dB/100 ft @ 900 MHz (much lower than RG-58)​

• Operating range: DC–6 GHz, with 80% velocity of propagation​

• UV-resistant PE jacket, designed for 20+ years outdoors​

• Temperature range: -40°C to +85°C

LMR-195-DB Cable vs Standard RG Cables

The LMR-195-DB cable offers dramatic improvements in attenuation, shielding, and environmental resilience over standard RG cables such as RG-58 and RG-142. Its water-blocking feature ensures signal reliability in harsh, wet, or underground scenarios, making LMR-195-DB cable the best choice for outdoor and buried RF applications versus legacy RG designs.​
