The 8DFB cable is a popular choice for applications requiring high-frequency signal transmission with low attenuation and good shielding. It is often used for connecting antennas to equipment, as well as for distributing signals in broadcast and communication systems.

Specifications

  1. Impedance:
    • 75 ohms: This is the standard impedance for broadcast and video applications, ensuring compatibility with a wide range of equipment.
  2. Frequency Range:
    • Typically supports frequencies up to 3 GHz or more, depending on the specific cable construction and quality. This makes it suitable for various RF and broadband applications.
  3. Attenuation:
    • Low Attenuation: Designed to minimize signal loss over long distances. For 8DFB cables, attenuation values are typically around:
      • 1 GHz: Approximately 4.5 dB/100 meters
      • 2 GHz: Approximately 6.5 dB/100 meters
      • 3 GHz: Approximately 8.5 dB/100 meters
    • Exact values can vary based on the cable length and manufacturer.
  4. Shielding:
    • High Shielding: Provides excellent protection against electromagnetic interference (EMI) and radio frequency interference (RFI). Typically includes:
      • Foil Shield: A layer of aluminum foil to block interference.
      • Braided Shield: A layer of copper or aluminum braid for additional shielding effectiveness.
  5. Dielectric:
    • Foam Polyethylene (PE): The dielectric material is often foam polyethylene, which helps to maintain impedance and reduce signal loss.
  6. Conductor:
    • Material: Usually made of copper or copper-clad steel. The conductor is designed to provide good signal transmission with minimal resistance.
  7. Jacket:
    • Material: Typically made from durable materials such as PVC (Polyvinyl Chloride) or PE (Polyethylene). The jacket protects the internal components from physical damage and environmental factors.
  8. Construction:
    • Outer Diameter: Approximately 8.0 mm (hence the “8” in 8DFB), though exact dimensions can vary slightly based on the manufacturer.
    • Inner Conductor: Solid or stranded copper or copper-clad steel.
    • Shielding: Multiple layers for effective protection.

Applications

  • Broadcasting: Connecting antennas to broadcast equipment.
  • Satellite Communications: For satellite dish installations and signal distribution.
  • Telecommunications: Used in various telecom systems for signal transmission.
  • Video Transmission: Ideal for video applications due to its low attenuation and high shielding.

Performance Characteristics

  • High Performance: Maintains signal integrity and minimizes loss over long distances.
  • Low Loss: Ensures minimal signal degradation, even at higher frequencies.
  • Robust Shielding: Provides excellent protection against external interference.

Considerations

  • Connector Compatibility: Ensure that the connectors are compatible with your equipment. Common connectors for 8DFB cables include BNC, F-type, and others.
  • Cable Length: Select an appropriate length based on the application to avoid excessive signal loss.
  • Environmental Factors: Consider environmental conditions if the cable will be exposed to the elements or physical stress.
