I bought a crimper and 4 hole die. Which slot should I use to crimp TWS-240. They are marked .255, .187, .068, and .213
This is a question I should of asked when buying but slipped my mind.
Since you didn't say what type of connector, just what type of coax, it's kinda hard to say. Here's a search that may help you find what you're looking for since you have the necessary information not us.
Thanks for the replies. I am not sure what connections I am going to use yet but probably bnc, uhf and probably N. I will be buying a ftm-400dr and building a qrp rig So I'll need some options.
