Poor Design Type N Connectors
The type N connectors used on this cable are a poor design. If torque is applied to the cable after the connector is mated it's possible to shear all the shield braid wires. After this happens the connector does not readily come off the cable, but it's performance is ruined. To test for this, with the connector disconnected, hold the back of the connector (near where it attaches to the cable) and turn it a few degrees. If it rotates freely it's already bad. If you pull a bad connector it will come completely off the cable. For this reason it very important not to apply ANY torque to the cable once the connector is mated. There are Type N connectors that are molded onto the cable that also incorporate torque, strain relief and weather protection. These would be much better in this application. Of course with the existing connector, when it fails, the same connector can be reinstalled on the cable.
