I bought my Antenna cable (RG-400), BNC connectors and RCT-2 Crimp Tool from B&C Speciality.
I have never crimped these connectors before and whilst I haven't fired up the radio/transponder yet the continuity checks show I have done a good job.
The connector comes with a diagram for stripping the cable (I used a model knife) and on the RCT-2 I used 0.068 for the centre pin crimp and 0.213 for the ferule crimp.
