The long ones are typically blue and labeled "12 AWG". They look a lot like RG-8/213 types. There are some skinny jumper cables on the CI panel internals that look to be a much skinnier kind of coax, also blue, looks like RG-174. In the "real world" I am much more likely to see LMR-400 or Belden 9913 specified today, than the RG-type specifications. Tim.
