TDR measurments are not significantly affected by wire being coiled. If it had ferrite sleeves on it maybe, but not just coiled, and certainly not a large diameter coil. Youll likely have a greater error from temperature.
I can't imagine anything on the outside of the coax (ferrite sleeves, iron pipe, anything) having an effect unless it's coax with a leaky shield. (they actually make deliberately leaky coax, for things like distributing radio signals in mines and tunnels)
