This short video shows how to install a crimp style BNC connector onto RG-58 50 ohm coax. Installation of other crimp style coaxial connectors will be similar. Note that the connectors are specific to the type of coax being used, and having the correct crimping tool is really a necessity. You can optionally (carefully) solder the center pin, and optionally finish up with some heat shrink tubing for clean professional look.
