Fun fact: the USSR used exactly the same technology and that is why enabled the US to monitor all phone calls using the Rhyolite/Aquacade surveillance satellite: microwaves are line-of-sight and due to the curvature of the Earth (take that flat-Earthers!), the inter-station signals continue into space and are receivable by a big enough antenna. https://en.wikipedia.org/wiki/Aquacade_(satellite) https://en.wikipedia.org/wiki/Aquacade_(satellite) Fun fact 2: back in the day you could make a "station-to-station" long distance calls - these are the "stations" they were talking about.
