that picture is well out of focus, but if the traces are undamaged, you should be able to replace the connector. I would find a wiring schematic for the board and do continuity tests to the pads and make sure they are still connected to the appropriate locations.
if this is a VTX, I would guess that the side 2 connectors are ground and the smaller middle one is signal. Ground obviously goes to ground and the signal is going to connect to an amplifier chip/IC (or some filtering discrete components after the amplifier).
if it is a RX, it would be a bit more complicated for the signal wire (given that most RXes are actually transceivers).
