Get the right tool

If you're a newbie looking at buying a cable tool to make terminations, be sure and buy a compression tool, as shown, not a crimp-on tool.

Also do not be afraid to buy a whole box of F-connector ends, they don't spoil and you'll end up using them all eventually.

This is Compression, Not Crimp

Great article, wrong name. You are showing a compression tool here, not a crimp tool. If article is renamed, it would deserve 5 stars.
