The RG-62 coaxial cable is a type of coaxial cable often used in low-power signal and data transmission applications, such as computer networks, radio systems, and instrumentation systems. Below are the general specifications and attenuation characteristics:

Specifications:

  1. Impedance:

    • 93 ohms (nominal).

  2. Dielectric Material:

    • Polyethylene (PE) or similar material, often foamed for flexibility.

  3. Outer Conductor:

    • Typically a braided copper shield or foil.

  4. Inner Conductor:

    • Solid or stranded copper-clad steel (CCS) or other conductor types.

  5. Outer Diameter:

    • Around 6.15 mm (0.242 inches).

  6. Capacitance:

    • 13.5 pF/ft (approximately 44.3 pF/m).

  7. Velocity of Propagation:

    • Approximately 84% of the speed of light (dependent on dielectric material).

  8. Applications:

    • Used in specialized data networks (e.g., ARCnet), high-impedance circuits, and instrumentation.

Attenuation Characteristics:

Attenuation (signal loss) depends on frequency and cable length. Below is a general guideline for RG-62 attenuation:

Frequency (MHz)Attenuation (dB/100 ft)Attenuation (dB/100 m)
1 MHz0.62.0
10 MHz1.86.0
50 MHz4.213.8
100 MHz6.019.8
200 MHz8.728.5
400 MHz12.741.7

Key Features:

  • High impedance makes it suitable for low-power transmission and low-loss applications over long distances.
  • Common in legacy systems like ARCnet, though it is largely replaced by modern coaxial cables in many applications.
