We have been having problems with pre-made BNC cables. The cause has been narrowed down to the fact that once the BNC is locked in place the cable can still rotate relative to the connector. This can result in the soldered core, or the shield, or both tearing free. The symptoms are a full or partial loss of signal or a major increase in noise.
The question being - how can I specify that the body of the cable is molded to the plug so that this problem is eliminated? I have found a suitable such cable, but as often happens it is apparently going out of production. Any suggestions?
