| You are in luck. You can use pretty much any cable you wish, just make it very short.

| From that table, you can see there are a number of choices. For a 12" cable, the cable loss will be low, BUT do add in around .2 to .3 dB of loss for each connector you are added on each end when chosing the cable.
