[Elecraft] BNC Connectors

[Jack Smith]

Buy a crimp tool and use crimp connectors.

Two types of crimp connectors are available, single crimp and double 
crimp. Single crimp uses a solder-in center pin and crimp shield and the 
double crimp version crimps  both the center pin and the braid. I have a 
slight preference for double crimp, but either are acceptable.

For connectors and crimp tools, you might look at The RF Connection in 
Gaitherburg MD. It's owned by a ham, and I've found them good to deal 
with. http://www.therfc.com/ is their web site.
