How far have earth’s radio waves traveled? Signals have gone out about 303 trillion kilometers, well past the nearest star. Here’s how to figure it out.
How far can a radio signal travel on earth? On the Earth it depends on the propagation mode: Ground wave – up to ~300–500 km. Skywave – depending on the angle of radiation it could be from local communication when radiating straight up and up to 10000–15000 km when radiating at low angle into the horizon.
Do radio waves go on forever? Why would it run out of energy? Space has so few atoms in even a cubic mile of space, and most radio waves don’t interact with them anyway. So 1/r2 loss is all you have to worry about. But this never reaches zero, so the wave just keeps on going.
HOW FAR CAN signals travel in space? Ground station antennas range from the small very high frequency antennas that provide backup communications to the space station to a massive, 230-foot antenna that can communicate with far-off missions like the Voyager spacecraft, over 11 billion miles away.
