Art,
Use a coax ratcheting crimp tool kit. Greenlee and T&B both make them, as well as numerous other companies. You might try WW Grainger, or any electrical wholehouse. Stay away from the old mash type connectors, loose connections build heat. Heat is electricity's #1 enemy. If you can't find them, send me a private message. I'll get you a catalog #.
