WebThe F10.7 solar radio flux is used to this day as a proxy for solar activity. One problem: A solar radio observatory that uses this frequency band needs to be far away from an airport. Airports also tend to use 10.7 centimeter radio waves in their radars because that's what was used back in World War II. Web7 mei 2024 · How far can radio waves travel in space? The greatest distance for a transmission by a human-built device is currently about 13,482,762,800 miles, and growing by the minute. The greatest distance over which radio signals can be received is some hundreds of millions of lightyears; radio astronomers do that regularly. Only about 100 LY.
