Steel conduit with bare grounding conductor

[ActionDave]

If the grounding cable were routed in a long conduit run vs just a stub up would that make a difference?

The choke effect, as I understand it, is related to Grounding Electrode Conductors and a lightning strike being a high frequency event. I'm sure there is a length where that matters, but I don't know what it is.

For what it's worth, all the work I've done at cell sites the bonding wires were sheathed in non metallic flex, but I don't think it would have mattered.

As far as worrying about a choke condition during a fault there is nothing to worry about. Ground faults in a commercial building can have hundreds of paths to follow, plumbing pipes, building steel, metal ductwork, sprinkler pipes, etc.
