The correct way is to throw away the connector and just buy a compression/crimp connector and tool (amazon sell them for £15)...you literally cannot pull them off...so when you go to refit your tv/sky box etc the wires don't fall out the back.
I almost had a meltdown with those twist connectors....they are just a really rubbish design I think....so much faff and then a poor signal.
Yea I had a serious meltdown with my sky connectors....almost ended up pulling all the cable out because I assumed it was the cable. Turned out to be the bloomin connectors!
I assume they do crimp normal coaxial too?...or can a connector be screwed on?
