IF you are only looking for LMR-400, Ideal makes a crimp tool called the crimpmaster. The part number 30-506 is the frame only. I suggest gettting 2 dies, one that does vinyl connectors 22awg-10awg which you should be able to find in the frame at places like your local electronics store as well as Home Depot, Lowes...The second die you need is one with a .429 hex crimp 30-577 it will do any of the EZ style LMR connectos.
