Does anyone recall the basic specs for "Amphenol No. 621-685" coax cable?

There are no other markings on the cable than that. It looks like RG-59
in size. Apparently Amphenol no longer make it and a Google search turned
up nothing.

Are you sure it's a coax cable? Strip it and see if you don't get lots
of carbon black on your hands in the process. If so, it's a low-tribo noise
cable and not good for RF. Amphenol made a bunch of different kinds.

Amphenol has not made any cables for at least twenty years, though, so
this is not recent production.
