RF connector model size
In general, the main name code of the universal RF connector adopts the main name code of domestic and foreign common use. The main name of a particular product is specified by the detailed specification and how the symbol is used.
The model number of the universal RF connector consists of two parts: the main name code and the structural form code, separated by a short horizontal line "-" in the middle. Other cases to be explained can be specified in the detailed gauge and separated by a short horizontal line from the structural form code.
