What is the correct way to represent coaxial cables in SW electrical and routing harnesses? I have an RG58 cables that are terminated with RPSMA's, FME's and UHF connectors.

I used single wire diagram for linking the connector to the aerial base with single wire diagram symbols

I created a cable with 2 cores and a shield.

I reserved cores for the component circuits as per attached image.

I created the connectors with only 1 Cpoint.

I couldn't see anything in the cable references manager to specify that it is coaxial and the circuits come up as blue (unused) in component properties. I think I'm missing something but I'm not sure where. How are Coaxial cables usually handled?
