I had previously purchased ferrite cores on the Internet. I tried to sow RG58U 6 times. I'm not sure if this will work, but I decided to give it a try.
This is a connector being attached to RG8U
Connectors sold here are probably made in China Chrome plated, not tin plated as in Japan This makes it difficult for solder to get on and off. File it down a little and then solder it.
