Standards

Most coaxial cables accept a appropriate impedance of either 50, 52, 75, or 93 Ω. The RF industry uses accepted type-names for coaxial cables. Thanks to television, RG-6 is the a lot of commonly-used coaxial cable for home use, and the majority of access alfresco Europe are by F connectors.

A alternation of accepted types of coaxial cable were defined for aggressive uses, in the anatomy "RG-#" or "RG-#/U". They date from World War II and were listed in MIL-HDBK-216 appear in 1962. These designations are now obsolete. The RG appellation stands for Radio Guide; the U appellation stands for Universal. The accepted aggressive accepted is MIL-SPEC MIL-C-17. MIL-C-17 numbers, such as "M17/75-RG214," are accustomed for aggressive cables and manufacturer's archive numbers for noncombatant applications. However, the RG-series designations were so accepted for ancestors that they are still used, although analytical users should be acquainted that back the handbook is aloof there is no accepted to agreement the electrical and concrete characteristics of a cable declared as "RG-# type". The RG designators are mostly acclimated to analyze accordant connectors that fit the close conductor, dielectric, and anorak ambit of the old RG-series cables.
