Hello to everyone. I have a question. Flat earthers do an experiment called the radio waves experiment in a fake science documentary called Convex Earth.They claimed that the antenna, which was broadcasting at a frequency of 5800 mHz and 1.5 meters above sea level, could not be transmitted to another antenna, which is 1.5 meters above sea level, 14.2 kilometers away from the curvature of the earth. But in their experiment, they said that the connection between the two antennas was ensured. I'm talking about the radio wave experiment going through this video between 0:14:23 - 0:16:08 and 0:42:06 - 0:48:26: Source: https://m.youtube.com/watch?v=McdMMmclGVc In addition, technical information about the experiment, this video is told between 0:05:20 - 0:06:23 minutes: Source: https://m.youtube.com/watch?v=eA793A1vnW4 What is the scientific explanation of this claim? Thanks in advance for your answers.
