This is aa 15cm RF bulkhead mount extension cable with RPSMA male/female terminations.
At one end is a RPSMA(M) fitting and at the other is a RPSMA(F) bulkhead fitting that allows mounting through panels to get the best antenna location.
The bulkhead fitting will allow approximately a 6mm wall thickness to be penetrated, with allowance for the lock washer, nut and terminating cable/antenna to be connected on the other side.
These cables can be connected end to end to make custom lengths (losses will be added together on subsequent cable lengths).
