My mistake. Sorry.

A good BNC should need quite a hard twist to make the bayonet click into place... and in old surplus plugs, this springiness does wear out." "....rubber washer inside the bayonet ring." sure doesn't sound like cable retention to me. Sorry for the confusion, I guess. On the other hand, when the rubber washer deteriorates, the connectors mate much more easily once, as the female contact is destroyed in the process. Ian, I suspect that is your failure mode, as I have chopped up some very old connectors, and the spring washers still seem to retain their shape, while the rubber is rotten. On the other hand, I have seen some cheapies which are soft from the manufacturer. I send those back. -- Crazy George Remove NO and SPAM from return address |
