[Elecraft] Type "N" connectors

[Brett gazdzinski]

We use crimp only at work.
Loads of BNC connectors on 45 mb DS3 cables, they 
get abused and never seem to fail.

We have a very expensive amphenol tool that crimps
the shield and center pins.

We also crimp the 48 volt power wires, 200 amp and so on,
very special tools for that, and the wire has to be correct,
they pulled out all the old welding cable and put in stuff
that is really hard to work with, hard and inflexible, but I
suppose it holds the crimps well.

I like solder, and its usually much cheaper than a good tool
and all the dies, but crimping done right is very good.

When some think of crimping, they think of spade lugs
with a cheap hand tool crimp...you know, the ones the wires
pull right out of...
