Surprisingly, yes! Signals in copper travel at about 0.7C, while radio in air travels at ~1.0C. (Light in fibre optic cable is also about 0.7C).

- madengr 5y agoThe signal travels in the dielectric between the copper conductors. If that dielectric is air, and it’s TEM propagation, it travels at 1.0C.
