The Davis RF Bury-Flex™ "Direct Burial" Low Loss Cable is a high-performance coaxial cable designed for direct burial applications without needing additional conduit. It is ideal for outdoor or underground installations, often used for ham radio, CB radio, and other communications purposes requiring minimal signal loss over long distances.

Key features include:

• Low Loss: This cable offers excellent signal retention, making it well-suited for applications where long runs are required, reducing attenuation compared to traditional cables.
• UV and Moisture Resistant: Built to withstand harsh outdoor conditions, including direct sunlight and moisture exposure, making it durable over time.
• Flexible: The cable is relatively flexible, making it easier to install in various conditions, including routing it around obstacles.
• Construction: It typically features a high-quality, tinned copper braid shield and a solid center conductor, which contribute to its electrical performance and durability.

This type of coaxial cable is particularly valued in amateur radio setups, broadband, and other communications systems needing a reliable connection with minimal signal degradation.

Here are the typical specifications for the Davis RF Bury-Flex™ "Direct Burial" Low Loss Cable:

• Impedance: 50 Ohms
• Capacitance: Approximately 24.5 pF/ft (80 pF/m)
• Velocity Factor: Approximately 84%
• Center Conductor: Solid copper conductor (usually 10 AWG or 7-strand copper)
• Shielding: High-quality tinned copper braid (usually providing at least 95% coverage)
• Dielectric: Foamed polyethylene
• Outer Jacket: UV-resistant polyethylene for durability and direct burial
• Outer Diameter: Typically around 0.405 inches (10.3 mm)
• Loss (Attenuation):
  • At 10 MHz: Approximately 0.65 dB per 100 ft
  • At 50 MHz: Approximately 1.4 dB per 100 ft
  • At 100 MHz: Approximately 2.0 dB per 100 ft
  • At 450 MHz: Approximately 4.4 dB per 100 ft
  • At 900 MHz: Approximately 6.5 dB per 100 ft

Applications: The Bury-Flex™ cable is suitable for HF, VHF, UHF, and microwave frequencies, making it ideal for amateur radio, Wi-Fi, cellular, and other communication systems needing minimal signal loss and robust performance.
