I have a jumper cable in an equipment rack with those markings that has been pinched and severed, needing to be replaced. Anyone happen to know the specs on the cable?

Pictures and/or relevant info on the application would be quite helpful.

Cameras not allowed on site. It is a jumper from a receive multi-coupler to an alarm data receiver. The cable fits in a ug-176 adapter not a ug-175(had them handy for comparison). It is a black rubber jacket, bare copper braid, foamed inner, very fine single strand copper center, BNC connectors on both ends. No one is sure if it is an original cable or a replacement cobbled together by a past technician. I have an LMR240 jumper in place now but it "doesn't look the same".

And the answer is 93 ohm.

Found the card for the tech that used to service the system. He said it was a cable he had on his truck left over from a computer networking project that was the right length so he didn't have to take time to make a replacement at O-dark-thirty and forgot to go back and change at the next scheduled service.

The LMR-240 is staying put.
