Davis RF RG-58/U coaxial cable

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
