Alinco radio coax connector
 

My Dr 590 has two connectors one for vhf one for uhf. WHile hooking an
antenna up the connector actually came out of the vhf. I looked but
could not see any wires in there. I put it back in and at least
according to my swr it was putting out wattage.

How do these things go on and do I need to do something different? DOes
it need to be soldered?
