I have a 30 metre length of large diameter coax which I need to
identity to ensure I get the correct connectors.

The cable is about twice as thick as RG213, and has the following
parameters.

Sheath is 22mm OD black PVC. or PE
Inner conductor is a single solid 5 mm dia copper conductor
Outer conductor is bare copper braid.
Dielectric is solid polyethylene

Download in a few seconds from website below, programs COAXPAIR and COAXRATE
to obtain from dimensions all the performance data you need. The only info
they don't provide is the manufacturer's type number.
