What does RG rating mean?

Coaxial cables use RG ratings to distinguish between the different kinds of cables. RG is an old, mostly forgotten military term that stands for “radio guide.” The number distinguishes the different cable specifications, but they are randomly assigned, so don’t look for some type of order in the numbers.

What is RG 188 cable?

RG188 Coaxial Cable is a 50-ohm coax cable ideal for use in a variety of applications, including direct burial applications. This cable features a silver-covered copper-clad steel inner conductor, solid PTFE dielectric, and a white Type VIIA PTFE jacket as specified by MIL-C-17.

What does the U mean in coax?

RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. RG was originally a unit indicator for bulk radio frequency (RF) cable in the U.S. military’s Joint Electronics Type Designation System. The suffix /U means for general utility use.

What is RG rating on coax?

When referring to different types of coaxial cables, RG stands for “Radio Guide,” a designation derived from World War II military specifications. Each type of coaxial cable has a different RG rating to help distinguish the cables’ distinct characteristics and specifications.

What is the difference between RG6 and RG6 U cable?

When it comes to RG6 and RG6/U there is really no clear or distinct difference between the two that anyone can actually pin as solid fact. These cables can have extra shielding that make them last longer or work better than other RG6 cables while being used outside the protection of a solid structure.

What does u mean on cable?

RG316/U Coaxial Cable: Small Diameter, Large Fire Resistance. RG316/U designates a special form of coaxial cable. This coax cable has a 50 Ohm impedance (figure 1), making it ideal for data transmission.

What does the U mean on coaxial cable?

RG, or Radio Guide, is the original military specification for coaxial cables. Different types of RG ratings for each type of coax cable help to distinguish the distinct characteristics and specifications of the cable. For example, in the designation RG#/U, the U indicates general utility use.
