RF signal generator Ground connetion?

I have built this signal generator http://qrp.gr/rfgenerator/ inside a metal enclosure. The enclosure is connected to the ground of the PSU and the RF. The pcb is enclosed at the back of the enclosure and the two RF output connectors are located at the front panel. I intend to connect them with a coaxial cable to the PCB. The connectors grounds are attached to the enclosure.

The question is: How should I do the grounding on the coaxial cables?
Connect the shield to the PCB ground side only and leave the connectors side unconnected?
Connect the shield to both the PCB ground and the connectors body?
Connect the shield to the connectors body only and leave the PCB ground unconnected?

If you have seen a few RF instruments, you surely know the answer. Coaxial cable screen should be always grounded at both sides.

I was not sure. Thanks that simplifies things.
