This is just a thought experiment. Suppose I could make a perfectly straight tube 100 km long. I then created a vaccum in he tube by removing all sir from the tube. Into that tube with a directed antenna I inject a wifi radio signal. Is it possible that the signal would reach the end of the 100 km vaccumed tube unattentauted - except for maybe munus 5%. I am asuming that the tube is heavily insulated on the outside with a "dielectric and is made of a metal like copper on the inside. The idea is can a vaccuum overcome attentaution of radio signals.
