RG58U Coax 50 ohm Cable 92% Braid

The connector typically used on this wire is BNC-RG58.
With a 50-53 ohm impedance, this wire doesn’t meet the Thinnet™ standards, for a better Thinnet™ cable see CAB-THINNET™. CAB-THINNET™ is also recommended over this for antenna wire (for wireless networking).
This wire has a PVC jacket rated to 80° Celsius, see CAB-RG58-PL for a Plenum equivalent.
