I believe that many users in the procurement of RF wire, will encounter such a problem, that is - RF cable quality is good or bad how to distinguish? The distinction between rf cable quality and quality is not complicated, there is a simpler standard to distinguish
Wire is divided into positive and non-standard lines As the name implies, the quality of the positive line is certainly better than the quality of the non-standard line and the positive line can pass the U.S. standard UL certification standard
