M17/RG-278

The M17/93-RG178 coaxial cable is a 50-ohm cable commonly used in aerospace and wireless communication applications. Below are its key specifications:

Electrical Characteristics:

  • Impedance: 50 ohms
  • Capacitance: Approximately 29.4 pF/ft
  • Velocity of Propagation: 69.5%
  • Voltage Rating: 750 V RMS (per MIL-Spec)

Attenuation Loss per 100 Feet:

Frequency (MHz)Typical Attenuation (dB)Maximum Attenuation (dB)
10027.229.0
40055.058.0
100090.095.0
2400135.0145.0
5000200.0220.0

Note: These values are approximate and can vary based on manufacturer and specific cable construction.

Power Handling Capability:

Frequency (MHz)Maximum Power Rating (W)
50380
100253
200170
400113
70081
90070
100066

Note: Power ratings decrease with increasing frequency due to higher attenuation.

Mechanical Properties:

  • Conductor: 30 AWG stranded silver-coated copper-clad steel
  • Insulation: Polytetrafluoroethylene (PTFE)
  • Shielding: 95% coverage silver-coated copper braid
  • Jacket: Fluorinated ethylene propylene (FEP)
  • Overall Diameter: Approximately 0.071 inches (1.8 mm)
  • Minimum Bend Radius: Approximately 1 inch
  • Operating Temperature Range: -70°C to +200°C
  • Weight: Approximately 5 lbs per 1000 feet

These specifications make the M17/93-RG178 cable suitable for high-frequency signal transmission in demanding environments.
