The Davis RF RG-58/U coaxial cable is a type of RF coaxial cable commonly used for general-purpose RF transmission, antenna connections, and other applications requiring relatively low signal loss over moderate distances. Here are its typical specifications:

Electrical Specifications:

• Impedance: 50 ohms
• Capacitance: ~24.5 pF/ft (~80.4 pF/m)
• Velocity Factor: Approximately 0.66 (depends on dielectric used)
• Frequency Range: Suitable for frequencies up to about 1 GHz (performance may vary with length and use case)
• Maximum Voltage Rating: Generally around 1,900 to 2,000 Volts (peak, depending on specific product variants)

Physical Specifications:

• Outer Diameter: Approximately 0.195 inches (4.95 mm)
• Center Conductor: Stranded or solid copper (typically 20 AWG)
• Dielectric: Solid polyethylene (typically white)
• Shielding: Single braid shield (copper or tinned copper braid)
• Jacket Material: Often PVC (polyvinyl chloride) with UV-resistant variants available for outdoor use

Typical Uses:

• Amateur radio
• Antenna feed lines for mobile or base stations
• Low-power RF and signal applications

It is important to confirm exact specification
