Due to the quad shielding, this wire cannot easily enter the connector/crimping tool, so it needs to be lubricated and slowly inserted into the connector before crimping. If you don't do this, the center copper wire will not connect to the jack socket on your receiver/TV and you may have a problem. Of course if you use the plugs that come with it most likely there won't be any problems but I like to plug it into a TV/receiver and then trim it. Every additional meter of cable has a loss factor.
