How do radio waves travel to the opposite side of the planet? How do they overcome the curvature of the earth?

Question

Does the signal simply pass through multiple radio towers?

In: Technology

Answer 1

To overcome the curvature there are basically two methods.
The first one uses reflection. At certain frequencies the higher layers of the the atmosphere will reflect the signal and this way you can reach areas that are over the horizon. Ham radio operators are doing it for example.
The second, more modern method is using satellites. You send a signal to a satellite and it will recieve and forward it
