WiFi 2.8 GHz Signal Loss Connectors vs. Solder?

Question

As far as signal loss is concerned is it better to use connectors when splicing a coax cable (which I don't currently have) or if I solder the two together is this better anyway. The cable is going from my router to an outdoor antenna but it is in two legths, one with a connector for my router and one with connector for my antenna and cut ends in the middle.

Thanks

Answer 1

soldering is going to leave the cable unbalanced at the join, you can not duplicate the impedance of coax after joining it. Use proper connectors.
