What is the Diameter of Coaxial Cable in mm?

Published in Cable Specifications 1 min read

The diameter of coaxial cable varies depending on the specific type of cable. Here's a breakdown based on the provided reference:

Coaxial cables come in various sizes, and their outer diameter is an important factor in determining their application. Here's a look at some common types and their diameters:

Type Impedance (ohms) Outside Diameter (mm)
RG-6/U 75 6.86
RG-6/UQ 75 7.57
RG-7 75 8.13

As you can see from the table, there isn't a single diameter for coaxial cable, but rather a range of diameters depending on the specific type of cable.

  • RG-6/U: This type of coaxial cable has an outside diameter of 6.86 mm.
  • RG-6/UQ: This variant is slightly thicker, with an outer diameter of 7.57 mm.
  • RG-7: This type of coaxial cable is even larger, featuring a diameter of 8.13 mm.

It's important to note that these are just examples, and many other types of coaxial cable with different diameters exist. When selecting coaxial cable, consider the application and the required signal transmission characteristics, as well as the cable's mechanical properties.
