I accidentally moved my PC while the antenna cables were caught on something, leading to them ripping. would I be able to just solder the connector bit to the cable?
These look like sma-male connectors. you’ll need to re-terminate them, you’ll need new connectors and a crimper, but it’s really easy to do.
If those are for WiFi they might be sma male reverse polarity, same crimper, just a different connector.
