123: Coaxial cable and connections

Coaxial cable also called coax is one type of network cables with an inner conductor surrounded by an insulated layer and a conductive shielding and used to convey data, video and voice.

Coaxial cable types (common):

1- RG (Radio Guide): RG stands for Radio Guide (Radio Frequency cable (RF)) and the number after the letter indicates the diameter in inches.

  • RG-6 (75 Ω, 18 AWG, solid)
  • RG-8 (50 Ω, 10/12 AWG, solid)
  • RG-11 (75 Ω, 14 AWG)
  • RG-12
  • RG-58 (50 Ω, 20/24 AWG, stranded)
  • RG-59 (75 Ω, 20/22 AWG, solid)
  • RG-62
  • RG-174 (50 Ω, 26 AWG)
  • RG-178 (50 Ω, 30 AWG)
  • RG-213
  • RG-316 (50 Ω, 26 AWG)

2- LMR

  • LMR-100
  • LMR-195
  • LMR-200
  • LMR-240
  • LMR-400
  • LMR-600

Note: The number after the letter (LMR) indicates the outer diameter in inches.

Coaxial cable based on the core type:

  • Solid
  • Stranded

Coaxial cable based on impedance:

  • 50 Ω (ohm): for data and wireless communications
  • 75 Ω (ohm): for video signals

Coaxial cable parts:

  • Center conductor (typically a copper wire)
  • Inner dielectric insulator
  • Metallic shield (Copper braid)
  • Outer plastic sheath (jacket)

Coax connector shapes:

  • Male: with pin
  • Female: with hole
  • Male RP (Reverse Polarity): with hole
  • Female RP (Reverse Polarity): with pin
